If you don't plan on going bigger for awhile, then 2" spacers will serve you well and be cheap. That would let your run your 32's. I personally think body lifts look tacky and don't recommend them. Not to mention with the bigger ones you have to correct shifter geometry and such, which I guess isn't that big of a deal, but it its just one more issue to deal with.
Personally, if your new to wheeling, then I say do the 32's and have fun with it. Learn your rig and what your capable of. If you're not so new, then I'd just jump straight to what you want out of it. If you want tons and 38's, then do what you have to do rather than doing it in small jumps and wasting a ton of money.
Either way, you're going to want an unlimited specific lift if you're replacing control arms.
