Fixed!!!!
It had nothing to do with the rotors that I was complaining about in my last post. I replaced the wishbone, control arm, and inner tie rod. Then took it to a very highly recommended shop and had them change the rear tires and balance/4-wheel alignment. It drives like new!
As Pedro brought up in the beginning, the tires were PART of the problem. Rears were very very worn on the inside, which caused some o the car vibration. The rest...I'll never know exactly as I replaced almost everything up front
