I'd buy the FAR AIM and then an hour or two groundschool to brief you on local procedures with a local FI when you get there. As others have said, if you've got good RT, you won't struggle much.
Alternatively (or as well), buy the Western States airfield guide sold by Pooleys, it's got a good guide to all the local rules and regs in there. Also get hold of a local sectional chart; the airspace classification is a bit different, and it'll help get your head around it. (Even an out of date chart will help here, just remember to buy a new one when you get there!).
