Blake- on your alignment question... it isn;t impossible to align it, you just need to goto a good shop. Basically since you are changind the ditance between your axle and your frame without droping the axle down to "normal" hight your camber is going to be way positive (top of your tires lean outwards). This can be corrected by adding an aftermarket bushing. I do alignments at work all the time and the bushings we use are from a company called specality products. They are relativly inexpensive... the labor is the killer... i believe we charge .5hr on eather side which would roughly be 66 bucks to install the bushings plus the alignment. The spacers work real well... i have them on my rig, and are easy to install. You don;t have to worry about new shocks or extenders, but the travle of them is limited, nor do you have to worry about the brake lines.
I hope this helps a bit
