i've done the same thing =) looks great man. if its not too late, i would open it up and seal the edges so the light doesn't leak out of the side onto the reflector. the light should only come out of the projector, any of the light that leaks out will lead to glare which might piss off any oncoming drivers.
as far parts, pick up some projectors from a BMW, Audi, S2000, etc. get some OEM ballasts (Hella, Matsushita, Phillips, etc.). next, just some Phillips or Osram bulbs in 4100k temp. and you are good to go. I've got a diagram to make your own wiring harness as well if anyone wants to do it! (its not hard!!!)
