Need some alignment help

Yeah what you are describing is a lack of caster. I try to max my caster out so it tracks better and faster return to center. The down side is it will require some more effort on turn initiation.

How much preload did you add to your coilovers (total lift amount)? Did you get aftermarket UCAs too?

Once you go over 2" of lift, it's hard to get respectable caster numbers without aftermarket UCAs. For what it's worth, I set my coilovers to about 3" of lift with Total Chaos UCAs and was able to get over 4* of caster.

You have your alignment sheet you can post up?

 

Depends on driving style and preferences. You should definitely be close to factory recommendations, but because of bigger tires and lift, you definitely want the caster on the high side. I let mine go into the red on positive caster.
Also I live in the mountains (and drive like an asshole), so I need a tiny bit of negative camber (-.02 degrees) or I wear the outsides of my tires.
As for toe, since we drive RWD/4WD, you want to be ever so slightly toe in.
