If you can't find all you need in the above link, there is a guy over at Stovebolt.com who is real good in helping out on some of the parts that you have mentioned. If you go over there, click onto the Big Bolts forum.

As far as lowering your truck, I personally would just leave it like it is, but if I were to want it a little lower, I would just try Low Profile tires.
