some handling issues Options

[Zimluura]

so a while ago i got a wheel bearing fixed. and my car re-aligned. but the alignment shop couldn't get things 100% perfect.

Front : Right caster is stuck at 1.0 degrees when it's specified range is 1.3 to 2.8.

at first my car pulled to the right, and then they adjusted something else to compensate for the caster being un-adjustable. and after that it was only a very slight pull.

i've since been in a front end accident which the insurance company repaired (minor frame damage they said was fix-able). and the alignment seemed a little bit better.

so now it's like 4 months later. and the alignment is not horrible, but still a slight pull to the right. and i'm noticing a slight shudder in the steering wheel on braking. so i'm sorta worried that i've warped a rotor (again) and that it could be indicative of another bad wheel bearing (yikes, hoping that's not the case) and want to get some opinions on what i should do regarding repairs.

furthermore, i was planning this year to spend a bunch of money with dr.tweak for an awd conversion and a 2gr-fe engine swap. i love my car and want to drive it until i die, but if somethings messed up permanently it might be a better idea to get another...just saying that makes me tear up...

any advice??
