As noted, Camber is fixed on a solid axle. the only way it is adjusted is with offset/adjustable ball joints
Caster is adjusted by adjusting the pinion angle - See FSM
The big problem with high lifts and short arms is that your pinion rotates up quite a bit and shoots your caster in the foot.
Likely, to get an acceptable caster, you will have to sacrifice some on your pinion angle.
If you have adjustable control arms, adjust the bottom ones out, or the upper ones in (equally) so the pinion is closer to a stock angle, then your caster should be much closer to stock. but you may get driveline vibrations. pinion angle > caster
The stock adjusters on the Lower control arm mounts on the frame may help, but not all that much.
