Not too sure about the front wheel problem. You should jack up the car, turn the wheels and check for clearance.

As for the squeak when you go over a bump, is it coming from the rear? If it is, you should check your thrust arm (it's the one that goes parallel with the car from front to rear, it attaches to the bottom of the knuckle) on the rear suspension. I hope I'm not confusing you. Anyway, try spraying both connecting points with WD-40. This is a temporary fix, you'll have to replace it.
