Simple, how-to reloading page
http://www.rcbs.com/guide/printsteps.html

Assuming you already have a solid place to mount your press (and some nuts/bolts), or can build one, here's a simple list I'd recommend to begin reloading:

Lee Anniversary Reloading Kit (includes press, powder scale and measure, primer pocket cleaner, case trimmer, deburring tool, priming tool, case lube...might have left some others out)
Brass: you did save your factory brass, right?
Bullets, of your caliber and choice of brand/size
Powder, of your choice again. Look at some data, ask for recommendations. Hodgdon H4350 is pretty all-around
Primers: your reloading data will show which type, but I use CCI and Federal
Dies and shellholder: multiple brands are available, your choice of cartridge to reload: most die sets have a shellholder
Case Length Gauge: for use with trimmer included in Anniversary Kit

Other recommended tools/accessories:
Caliper
Hornady One-Shot case lube
Case tumbler and media
Reloading Manual

Maybe I've left some stuff out...but that should be enough stuff to get you going!
