Nigel's spot on with the sound conditioning of the room. Then I would make a choice between recording to a PC or a standalone DAW like a AW1600 digital 16 track, it's what I use and it's cool. You can probably pic one up on ebay for about $250. You will also need a good set of headphones, good condenser mic plus a pair of nice studio monitors.
There's tons of things really and once you start down the path of buying studio gear it never ends.
