Are you talking about the clip on the lower portion of the window switch panel? Mine broke off too, but I used an electrical ring connector. Fasten it with one of the screws on the switch panel, and face the crimp end like a tab. I'll take a picture the next time I'm in my car. Its not perfect, but it holds it in place.
You could get rims for $55-100 a peice at discount tire or wherever sells aftermarket rims.

Shifted belts in the tire, and bad wheel bearings can also make the car shake. But for all four rims to be bent, thats interesting.
