They're all going to tell you the first thing you have to do is answer this...
What kind of corals are you going to keep?
Different corals require different lighting. I'd just go with the maximum, and make overhangs of rock to make shadows for the lower lighting corals to sit underneath. I think the high-intensity requiring corals are like 8-10 watts per gallon... so for 35 gallons, you want about 350-400 watts. I haven't started messing with MH lighting yet so I can't help you there really.
