Here's what I have on my 37 gallon tank...true, it is a little excessive:
37gallon tank: drilled 6 1" holes with bulkheads, 2 for return/drain to sump, 4 for a closed loop system powered by a Gen-X/Mak4
20L sump: with baffles
Lighting: 400w HQI ballast, radium 20K bulb and a 250w Iwasaki 6500K bulb
Temperature control: 1/3hp chiller and a 200w Ebo Jagar heater, both on digital temperature controllers.
Skimmer: Aqua-C EV90
Auto-top off switch
Geo calcium reactor
Maybe some other stuff I forgot.
This is pretty excessive, and yes, it can be a lot simpler.
A good startout system would be the following.
29 gallon tank
175w 10K hanging pennant
DRILLED (i highly recomend this as it reduces bubbles in your tank which i found can harm corals, and it gets your heater, skimmer, etc, into the sump and out of your tank, i think its really ugly to see a heater personally) with a 20L sump.
Lots of water flow, i would recommend 3 or 4 of the biggest maxijets out there, its really hard to have too much, but very easy to have to little. You can hook these up to a few simple timers, so that you have some change in flow.
Good quality liverock. I'm personally fond of
www.paragonsales.com they have some of the best liverock around, and even with shipping its still cheaper then most local fish stores.
Fine sandbed. Either "southdown" sand if you can find it, or carib sea's oolite sand (like beach sand consistancy).
A GOOD BOOK!
A good quality heater like ebo jager. I have had 3 crappy heaters fail on me, 2 of which shocked the living crap out of me, the other filled my house up with smoke, not cool.
Don't waste your money on additives, most are gimmics that can be easily solved by a few water changes. The only one that I would reccomend dosing would be Kalkwasser, and make sure you get more info before you start, cause if you do it wrong you can wipe out your whole tank.
Not many fish. Maybe a clown and a dottyback. Keep the fish population very low.
Pacience!!!!!!
This list is assuming that you are going reef. Going fish only would be kinda suicide with this small of a tank.
LAY OFF OF THE ANEMONE's!!!! Don't try one until you have at least a year of keeping corals under your belt.
