The rear axle is not adjustable, it is what it is. Only if rear aftermarket adjustable length control arms have been installed could this be off enough to need any help and that is limited to just making sure the axle is square and its pinion angle is where it should be.
For the front:
Toe-in: .15 degrees +/- .15 degrees
Caster angle: 7 degrees for up to a 30" tire, +/- 1 degree. 4.5 to 5 degrees for 35" tires. 5-6 degrees for a 33" tire. This is not adjustable without aftermarket control arms except on very early TJs that have cam bolts on the lower control arm mounting brackets.
Camber angle: -.025 degrees +/- .63 degrees. This is not adjustable without aftermarket adjustable angle ball joints.
