I'm 'bout half way done with putting my lift on, and so far it hasn't too much trouble, besides getting my steering colum out, that was a pain in the rear. but other than that not too many problems. there are a couple of things that you will need:
floor jack- very helpful, better and a lot faster than using just a bottle jack
full set of metric sockets- you will need to have both regular and deep socket types, the ones your gonna use the most are the 14mm, 17mm, and for the lift's new bolts 19mm
open end/ box end wrenches- same thing with the sockets, your gonna need a full metric set for getting things undone like the steering shaft bolts, and the radiator monting bolts
hammer- this is come in handy for getting the old bolts out, use an old bolt about 6" long to help get the old mounting bolts out.
4"x4" blocks of wood- these are very helpful as spacers between the frame and body when putting in the graphite spacer blocks
Thats about all i can think of right now, i'll give you an update when i finish the rest of the lift, which should be by monday.
oh and you will also need a hole saw or a air driven grinder to make a new hole in the fire wall for the steering colum.
by the way i'm in the same boat as you are, my truck's card is still dead while i'm waiting for parts, but i went ahead and started putting the lift on even though my truck doesn't run
