I just wrapped up my RE 2.5" lift on my 93 YJ. What an adventure. Having a friend to help is a big PLUS. I live in AZ so rust was not a problem, in fact every single bolt came off with little persuasion. I don't have air tools but I do have an electric rattle gun. That thing helped tremendously.
A couple of things...
Remember that parking/emergency brake line. You might have to re-route it so you don't pull it out by the roots when you articulate down.
On the front don't forget your vacume lines to the front differential. I had to re route those also.
When installing boomerang style rear shackles from the RE kit make sure the knee of the boomerang is pointing forward... we got to do that one twice.
If you do not have a garage try the back patio.
Mom did not like it at first, then she came out and saw the jeep half lifted. She liked it after that.
TRY NOT TO LAY UNDER THE JEEP. If at all possible work from the sides and not under it. I don't trust anything to hold that jeep up except its own tires.
When you are working with the little tiny brake line connectors use a small hammer to bang the wrenches, don't try and muscle it... you might round it off. (not speaking from experience or anything)
Most off all, HAVE FUN, drink a beer. Kick back. YOUR LIFTING YOUR JEEP.
