Steve, here is a list of what you will need (from wall to tank), if you go with just the MH and no supp. lighting.
1.)Powercord(usually comes with ballast but not always)
2.)Ballast
3.)Wiring from ballast to pendant(probably included with pendant but double check)
4.)DEPendant(will include socket and reflector and probably glass)
5.)Bulb
6.)Ceiling Hanging kit
I dont know for sure if you will need the two PC fans. What was your plan for those anyways?
Like I said before, I think you should take a look around at some tanks before deciding on what you go with and model your choices after what you like....
