I know Im not near as experienced as wade, but I will give you some info and recomendations. Everything is just my opinion, and some of it is the safest easiest way to do something.
First, flow and current:
Try to get the biggest pumps to circulate the most water as you possibly can. People preach wavemakers but I wouldnt mess with them at this stage in the game. I used to have a 29 gallon before I moved everything into a 55 a while back. I didnt think about powerhead placement or pumps (because I didnt know what I was doing.) and after some learning, I regretted it. In a tank that small its hard to put some large powerheads in without tearing down the rock work. If I were you, I would get a (read one) very large (large meaning high gph) powerhead, place it in the middle and face the front glass of the tank. Pile rock around it and in front of it to hide it. You can purchase nontoxic epoxy to glue the rocks down, or just do what I do and stack them. (but keep in mind that you WILL be restacking a few stragglers that fall every now and again untill you get the placement right.) Keep in mind though, that if you go this route with a submersible powerhead, you will not be able to get any anemones unless you make the rock around it fairly tight. Anemones are good at getting sucked up and damaged by powerheads. However, having said that you can go a different route with an external pump (which are fairly costly) and sump. Sumps are a whole other bag of worms, and runs into more money. But this is alot easier to do maintanence on. But, at this stage in the game, I would go ahead and go the internal powerhead direction, and give up on the anemones untill you have been able to successfully keep some simpler (but still beautiful) species. Anemones are very hard to take care of and are not for beginners. Granted, like I said, I am not the most experienced reefer, but I have never been able to keep one alive for very long.
Some good websites for equipment and supplies are:
www.liveaquaria.com
www.marinedepot.com
www.thatfishplace.com
these three guys have some cheap prices and good customer service.
The powerheads that I recomend are (the high end models are at the bottom of the lists.):

The 901's are a good deal, 50 beans for 900gph is fairly reasonable.
http://www.drsfostersmith.com/product/p ... 2004+22788
The ever popular maxijets are killer little powerheads, the high model give up close to 300gph, and I would get a few of these guys and line them up against the backwall and face the front if you go this route.
Personally, I would get the aquaclear 901 and place it like i said above, and stack rocks around it to hide it.
secondly, I agree with wade about the seahorses, they are a royal pain. Beautiful but a pain. I would also be careful with the urchins, as they have a habit of turning rock into swiss cheese by chewing on them.
Third, are you sure those are turbo snails, I dont know much about daytona, but Im doubting it. I speak from personal experience when I say DO NOT put anything in your tank without knowing EXACTLY what it is, what it needs, and what it can do. You would never buy another animal on a whim without knowing what it is, so dont do it with sea critters as tempting as it is.
Fourth: That powerfilter can be a great asset or a headache. Keep it clean, and replace the cartridges at LEAST once a month, on schedule, religously. Do the same with your waterchanges, once a week, twice a week whatever. just make sure you are consistant with what you use, where you get it and how you make it. Some people are going to argue this next statment until they are blue in the face, dont listen to them. "Do NOT use your tap if you go synthetic salt." I would in fact do as wade says and use your sea water, just filter the crap out of it before adding it. However if you go the sythetic salt route here is the method that I do that seems to work for me. First the materials:
1. I buy RO/DI water from wal-mart. RO/DI stands for "Reverse osmosis, Deionization" It is a method of filtering water to 99.9 percent pure. You can buy a RO unit from any of the three website that I gave you earlier. But dont buy cheap, expect to spend in the 200 dollar range for one. However, having said this, it is much cheaper in the long run to do this instead of the wal-mart route like I do. I do it just because I have a hard time coming up with 200 dollars cold hard cash. Its much easier to drop about 10 beans a week on water. (yours will be cheaper, remember mine is a 55 gallon.) Anyways, when you go to wal-mart, look on the label at the method of filtration. It has to say "filtered by reverse osmosis and deizonization." If it says any other filtering method after it, then its still ok, just as long as it has those words, somewhere on the label it is good to use.
2. Buy a small, over fivegallon plastic trashcan.
3. Buy one or two small powerheads using the discussion that we had above, they can be cheapies.
Here is the proceedure. I do all of this every thursday.
1. 5 gallons of RO water from wal-mart.
2. pour all five gallons into your trash can (making sure its near a wall outlet.)
3. Put your synthetic salt in next and use your hydrometer (something else to buy) to make sure it is between 1.021 - 1.024.
4. put the powerhead(s) in the can and run them with the bubblemakers on. The little tube that sucks air to them, the instructions should say how to rig it up.
5. Run it overnight (it can stay circulating for a good while.) but the next day is a good rule of thumb.
6. siphon out 5 gallons of water (using a 5 gallon bucket)
7. pour the new water in.
This sounds like a royal pain, but its not bad, all in all it takes me around 10 minutes to mix the water, and another 10 to change it the next day. But, like I said, I have a 55 so I change out 10 gallons weekly.
umm..forgot what number is next..Five:
sythetic salts: I use Oceanic, but many people like Instant Ocean, reef crystals. If you go with instant ocean make sure it says "reef crystals" because there are two types. Not the normal bag with the clownfish on the front, but the bag that has all the corals on the front. (dont even think it has a fish on it.) it is a bit more expensive but contains alot more trace elements than just normal Instant ocean.
Six:
skimmers, what wade says hit the skimmer thing on the head. Check out the nano forums, most skimmers (large ones anyway) are made to be sump placed, but having said that, there are many good ways to rig one to hang on the tank, or buy them specially made to do such.
seven:
lights. Lighting is such an indepth subject and is VERY confusing, there are lots of ways to set up lights. There are two routes you can go, power compact (PC) and Halides.
Power compacts are cheaper, put off less heat, and are a little bit easier to maintain. Just remember to change bulbs about every 8 months or so. Your tank probably came with a full hood, throw it away. If you want a top on your tank (and you probably do.) put a clear glass top on it like this:

Run of the mill 29's are 30" i think. but if yours is taller it might be different. Just take the ole' tape measure to it. One other thing, buy a light timer, put whatever lights you have on at least a 10 hour on cycle. Some guys do 12 and 12, just depends on what you want to do.
Ill run you through the PC basics. PC's are cheaper than halides, cooler (temperature wise), and easier, but have their downfalls. I have PC's on my 55 and wish I had bought halides, but ill never afford them. With powercompacts, I think its best to get the highest wattage possible that will still fit your tank and wallet, I would say that about halides as well, but you can definatley go overboard on a 29 gallon with halides. Here are some good PC's.

The aqualights are cheap and do the job. They dont have moonlights (which are small lights that simulate the moon at nightime.) but these are not a necesity and, in my opinion, are just for show. Like I said before, youll have to measure your tank to see which will fit, but they will be the same size as your glass top, but if all else fails, you can call them and ask.
http://www.drsfostersmith.com/product/p ... 004+113176
This is what I have on my tank. Again, get the highest wattage that will fit. These have moonlights and you will have to buy a timer for them as well. Ok this brings up something else. when you purchase light fixtures like these, they will have a few power cords hanging off of them depending on what you get. Some will be for different sets of bulbs within the fixtures to turn them on independly of one another. (Ill tell you why in a minute.) and some will be for the moonlights. You will have to factor this in when buying timers, because each will need to be turned on independantly, at different times. Like I said, ill elaborate in a few minutes.

These are the orbits, they are the higher ends of the satellite models. They are a bit more powerful and a lot more expensive. Same rules apply.
Now, to elaborate on earlier. The reason for the on off variations is the fact that there are SO many different types of bulbs. Bulbs (MH and PC) have a kelivn rating, shown as eg. 10000k. This, correct me if im wrong somebody, means that the higher the rating, the bluer the bulb,. There are also bulbs out there called "Actinic" these bulbs are totally blue. Most people mix and match these bulbs to give a desired effect. What does this mean to you? Experimentation is what it means. Most fixtures come with bulbs, so unless you just want to drop some money and replace the bulbs, you are stuck with what they give you. Your best (with PC at least) is to mix 10000k with actincs half and half. (if you have 4 bulbs, 2 10000 and 2 actinic.) this is the way i have mine set up and its not to blue, and not too yellow or white. I had an all glass PC on my old 29 and the bulbs that came with it were 6000k and were super yellow.
Now we get into MH, and im not going to pretend to know much about them. I know the basics and from what I understand, pendants will be your best bet, though someone with more experience is free to correct me. Here are some pendants.

There are also some fixtures out there that set on top of the tank like the PC that we just talked about, these are fine except for the fact that they will probably boil your water. Halides put out LOTS of heat, and fixtures like that will require a chiller. Pendants are best because you can adjust the hight untill the temperature goes to desired level. You will have a slight temp drop after the lights go out (timers still apply) but it wont be much. So, having said earlier that I dont know much about halides, Im going to leave it to the guys that know what the hell they are talking about and keep my mouth shut.
Well, there you go, I hope something here helps you. I wrote alot because I know how frustrating it is to start something like this and wind up screwing the pooch because you didnt get alot of the facts. Hopefully I gave you good info, and if anyone else sees a mistake feel free to call me on it, I didnt do it maliciously, I probably honestly did not know.
So best of luck buddy.
