Unless you use Wilson Dies, you'll need a press to start out with. I'd suggest Flea-Bay, Craigs List or your local pawn shop, in that order.
There are a bunch of Rockchuckers on Fleabay right now btw.
Then you'll need dies and a whole raft of other stuff.
You might want to consider a packaged kit like RCBS or Lee or Hornady offers, that gets you started at a good price.
