Welcome!
Like Preacher said; there is a great write-up on lift options, which he linked. I am sure that you have/will be like all of us and browse the picture threads and do the whole :faint2: thing. There are a lot of options but if your looking for a cost effective street cruiser then go with spacers. If your going to do mild off-roading, look at Old Man Emu or ToyTec or MetalTech. But if you want to do it correctly and save money down the road, then purchase coil-overs and a nice rear end set up and hit the trails!
Best piece of knowledge is to rush into it. Take your time; read as many threads as possible; both on installation and also problems people have then make your decision!
