Hey Stang Girl,
Mustardjohn is right... I used to work for a tire shop and if one of the wheel weights fell off that can cause some serious shakes. Even a very small weight can make a big vibration. Have them balanced and the alignment checked as soon as you can. That should clear up some of your problems.
As far as the bent rim... Well, theres no way to straighten one of those cast aluminum rims that the new cars come with. I say if you can live with it, use it as an excuse to save up and get some new wheels
