You didn't mention which RE Kit, so I don't know what's in the box.
Here are some basics:
Your caster will likely be "off" from stock. Live with it as long as the front pinion angle is slightly down or straight in relation to the front DS.
Camber: Can't fix w/out using adjustable ball joints as this tracks the knuckle angle, which is affected by caster.
Toe in: 1/16" should do it.
Wheel center: With wheels pointed straight ahead, adjust drag link to center wheel.
Front Brake lines: Either replace them with longer, or relocate the hardline.
Rear Brake lines: Relocate hard line at the hose connection. Make new bracket.
Rear E-Brake: Relocate joint located just infront of left rear wheel. About 2~3" did it for me.
Disconnects. The "bolt" on the axle side of the swaybar link is
NOT a bolt, it is a pressed in stud with a reverse torx head. Just press it out.
Rear Drive Shaft. This can/will be a source of vibrations afterwards. Either drop the t-case 1", or shim the axle as needed, or both. You are looking for equal and opposite. I ended up using a Rusty's 1" crossmember ( No loss of clearance). Remove the DS from the T-Case and lubricate the dickens out of the slip yoke before assembly.
Some folks simply do a Hack~N~Tap SYE and install a double cardan drive shaft ( like the front ) and shim the rear axle so that the pinion is about a degree down from the driveshaft.
I didn't have a spring compressor when I did any of mine.
What I can tell you is that if it looks like a short cut, it ain't. Resolve that you will be removing the front DS, shocks, calipers (tie them up), drag link, track bar, sway bar, the lower control arms in the front, and anything else which prevents the front axle from hitting the floor. You will need to support the Frame of the truck about where the t-case is to do the front, and when you do the rear, support it just before the front spring purches.
I do the back 1st, that makes me feel like I've accomplished something before I do the front
Again, remove anything which might tear off. Breather hose, rear drive shaft...
