aw shucks, thanks dvskin, and you're a cutie too, darn, too bad you live 800 miles away
lighting: i think the consensus would be metal halides if you can afford it with vho atinics...try to have your total wattage in the >5wpg range and you'll likely be able to keep most anything you want. filtration: a deep sand bed and refugium will go a long way...i personally would try to avoid getting a dependence to bioballs or carbon or something similar as you'll just wind up wanting to ween yourself off them later. for your sump/fuge it really depends on what sort of stand you buy/build. dvskin's comment about a 55 gallon fuge really isn't unreasonable assuming your stand doesn't have walls/supports in a way that makes it impossible. or you can always take the rubbermaid approach...
good luck, and don't forget to post pictures for all us small tank folks who like to dream
