how big do you want to go? Remember getting the 33's to match that lift will add ANOTHER 3 inches to the trucks height.
I didn't notice a big difference with turn radius when I put my spindles on. In fact I don't think it changed at all. Brake lines shouldn't be an issue. I'm sure with some phone calls and a little search there will be a company in your area that can manufacture new lines for you for relatively cheap.
Oh, and don't run blocks in the rear. Most 2wd's have a weaker softer spring that will not take the abuse of a block. If you run the full 5.5 system you'll want to get some Deaver Softrides or something like that. If you just run a spindle then you can use a Ford Explorer rear spring and a belltech shackle and you'll get the results you want.
