Tips/Helpful Hints/Suggestions on installing new shock absorbers

Hell, the springs are easy enough to put in, looks like they have the front bushings in them, get a set of rear bushings from your local part store (under 20 bucks), do it yourself and save even more! Just clean the threads on the U bolts before you take the nuts off and it shouldn't take you half a day to do everything.

As far as installing the leafs, do you jackstand the rear diff/axle as well as the frame to take weight off the springs to remove them?
I've never seen or done this before, so bear with me.
