I again have to agree with the frog dont go nuts on detail it'll put you off.
I agree 400watts of light is what ull need for a small set up 250 Hps would do but are probly more expensive than floro's aldo basementlighting in the uk offer some good prices and ive used them so uill recamend them,, Id rather buy a bag of Bio Bizz light mix myself as it has Nutes added for the first 3 4 weeks plus its pH IS PRE TESTED. Mylar is very good for reflecting light. Amen
Work on some Northern Lights or Pure Afganie
