Need complete stereo help starting with preamp

I recently bought a Rega P3 planning on upgrading my whole conventional JVC system and don't know where to start. I am limited on space for speakers although am trying to fill a fairly large room with sound. I am planning on purchasing either some 601 B&Ws or something a little larger and do not have much understanding of amps/preamps. Do I need to buy a phono preamp and a preamp to go along with whatever amp I choose or is that neccesary? Would I be better off buying an integrated amp/preamp? I would like to spend under $1000 on my amp/preamp combo to get me started. What would you guys reccomend in that price range? (it does not neccesarily have ot be new equipment) Thanks in Advance!
