Front alignment questions...

[OldSch88L]

Ok, I've been researching for long enough now that I'm getting confused... I got my truck aligned after my 4.5" lift. I had to go to a new shop, as the reputable shop that aligned my Jeep all those years in the past now refuse to touch modified vehicles. I didn't get a printout from that new place after the alignment but did get a glance at the screen before they got my truck of the rack. I remember seeing around 9.7 to 9.8 degrees of caster. With that lift, my wheels weren't centered in the fenders, so I maxed out my lower control arms forward, with the tubular 16.25" lower arms and WJ stock uppers. Now the steering is really vague in the center, compared to before with my 3" lift setup. So I'll take some shims out to dial it back around 7 degrees caster. My question is: am I wrong, or does playing with caster also affect the toe? And also, after some settling from the front suspension, my track bar adjustment now seems off. Other than steering wheel centering, will track bar length changes affect other specs?
