Go to a manufacturer's website. Something like Rusty's, Rubicon Express, etc. They'll have instructions to the procedure. It really isn't too complicated. Some info off top of my head:
-Use jackstands
-Jack up high enough to get coils out w/out compressors (shouldn't need until 4")
-Be careful of brake lines (may need to unbolt, pull out slack, rebolt in front @ 2")
-Shouldn't need a t-case drop @2" - hang onto it and see if you're getting new vibrations in the rear
-Soak the shock mount bolts in penetrating oil daily for a week or so to make sure they'll come loose
-Get an alignment from a shop after
-Go over and re-tighten all bolts after a couple hundred miles
It's mostly just: go slow, be safe, use jackstands. You may need to unbolt the trackbar and/or loosen the bolts for the control arms in the front to get the springs in and out. If you're just using spacers and stock coils it shouldn't be an issue.
Oh yeah, check out greatlakesxj for links to all kinds of write-ups and manuals.
