I saw somewhere on here that the passenger side will sit a little lower with no one in the car - designed that way so that when there is someone in the driver's seat it will be level. I've noticed it on a couple cars so can't imagine that it is anything abnormal.
Negative camber normal.
Hopefully you found my thread on the brake squeaking
