and is a penatrant that helps to get stuck and old bolts out.
for 2.00 a can - it cant hurt to have around
NO- it isnt the same as WD-40
YES-Liquid Wrench is an inferior product
Your front driveshaft should do just fine - though you *might* have to take it off depending on what SYE package you got. Checking the u-joints isnt a bad plan.
The Haynes/Chilton manual has a decent explination on that.
When you set up your front driveline, the control arms determine the driveshaft angle as well as the castor angle.
here is more than you ever wanted to know about driveline - but remember that you cant change the castor other than with the control arm lengths - so when i set mine up:

i picked a happy medium and ended up with something like 3* castor and 11* pinon angle when i really needed 13* pinion angle and 6-7* castor.

also remember to budget $$$ and time after the lift to get an alignment for tire wear, death woble cure, and to center the steering wheel.
to adjust your steering wheel to get to the alignment shop:

budget more time than you think you'll need, however, working on one end at at time (front or rear) would be the best idea, because you can drive a 1/2 lifted jeep for a week while you wait for time to get the other half done.
I have no reason to believe that a bolt on lift would take a first timer more than a weekend - especialy if someone who is going to be helping you has done one before.
Also a 1/2" ? drill bit for the Upper Control Arm Drop Brackets is a good idea to have around.
