Unhappy Car vibrations at all speeds, Know i have a bent wheel plus..

I installed urethane motor and transmission mounts, I used to get this vibration at 70+ mph but now I am getting them at ALL speeds its pretty severe, If you were to have change on the dash it would be bouncing around thats how bad it is, So i jacked up the car and ran it with the rear wheels off the ground and noticed my driver side rim is bent pretty bad, and the passanger rear is bent also but barely, also my tires are not balanced, and one more thing i noticed my drive shaft has a wobble to it when the car is in drive and the wheels are off the ground spinning, i tried to move the drive shaft up and down side to side and i tried to spin it to see if there is any play in the u-joints and they wouldn't budge, so i dont think my u-joints are bad, I think maybe installing the mounts make it more noticeable that there is a problem, the car does this even when coasting with the engine off, so what im asking is whats your opinion on what could be wrong and why the drive shaft would wobble like it does under load, thanks guys

a suspension vibration that causes loose change to jump around would rattle your teeth. and a bent wheel wont really cause a vibration at lower speeds, more of a wop wop wop kinda noise accompanied by minor shaking.
id check the harmonic balancer, then correct your wheel problems.
btw, having a car on stands and putting it in drive is not a 'load' condition.

Vibration is still there, i got all the wheels balanced and the bent rim fixed and my drive line doesn't have a wobble after all, it has a very tiny wobble towards the front of the driveline only where it comes out of the tranny.
