Welcome to the clan. I admire your decision to delve into real cameras, great way to learn the basics. The inverse is, its also a good way to become frustrated. Keep your eyes open for a Calumet CC-400(standard bellows) or CC-401(long bellows)4x5, they usually run well under $200(with accessories). You will definitly need a sturdy tripod, a handfull of film holders, and a decent quality lens. I used to develope film in trays, it works well if you dont mind spending long times in pitch dark.
Get some D-76 developer, stop bath(or water), fixer, and a rinse agent(I prefer Edwal LPN)and dont forget to get a good darkroom manual.
cheers
