As for places to buy lights, I'd check out the sponsor's forums here and see what they have to offer. Also, member's are always selling some of their stuff as well so maybe you can check out the equipment for sale section of this forum to see what's there. As for lighting options, there are many types out there. For fish only setups, you don't need really intense lighting like metal halides or anything like that. All fish really require lighting for is to differentiate between night and day (like it is in the wild) and also to process vitamin D. In a case like this, people tend to go with either power compacts, vho's or T-5's. Where an anemone will be thrown into the equation I think they require a bit more intense lighting than just fish will require. I once had an anemone under power compacts and I honestly can't say if he was doing well as I didn't really have him long enough to tell (maybe 6-8 months). By looking at him, I'd say he looked like he was doing well under the lighting as it grew some etc, but couldn't say for sure. I guess the others will chime in soon to offer their advice on that. Good luck! 
Maybe in a couple of years once I have these dang cars paid off, I can start over again
