Elroy,
It does sound fine. You won't be able to get the caster into factory specs and it really isn't a factor on a lifted vehicle, just make sure they are even or match.
Your camber is fine and for some reason, the right side won't go much lower than .5 and this could be due to centerlink wear.
Not sure about the aftermarket steering setups but I do know with my heim centerlink I can get my camber to go negative.
Hope this helps,
MVM
