That depends on what type of corals you want to keep.....I recomend you get a good reefkeeping books...please guys help a future refer picking a good book...
I have a 72 Bowfront and I use 2 175 watt MH. with german 10k's and everything is thriving. I have a couple of different types of mushrooms. I also have Pulsing Xenia and a Large toadstool. I have a green open brain and a gorgian . Also have a Large plate coral . In the past three months since going to the new light bulbs my mushrooms have started mulipling and the toad also has a small offspring starting to grow. I would highly recommend the MH's for this size tank
I think you should reconsider the anemone. They are best suited for anemone-only tanks. They tend to wonder around and burn the h*ll out of the corals. Moreover, they generally need very intense light. Much more than many corals out there. Finally, there are very few anemones that do well over the long term (>18months).

As for the lighting, I had 2x175 MH and 2x40 actinic over my 75. Then I upgraded to 2x250MH. The softies didn't like the extra light, but the SPS's did. Now I have 2x400 over a 120. It is your call. I would recommend VHO actinics though (over the normal output lamps).
It all depends on the type of corals you want. Soft corals, SPS, LPS, calms, anemones, etc.
As far as good books are concerned, I have 2 that are pretty good. Both are by Barrons, one is for getting started with reef-keeping (Marine Reef Aquarium Handbook by Robert Goldstein) and the other deals specifically with coral keeping (Corals by John Tullock). I've also heard that the New Marine Aquarium book is pretty good for beginners. HTH
I guess it depends on where you live, but I ran 2x250 without a chiller. The tank temp never reached 80F. More than I can say for the dual 400s I have now.
