SOURCE: front end vibration
It sounds as though your car has two seperate problems. The first problem with the vibration that goes away when you let off the gas pedal is caused by a bad INNER CV joint. It only vibrates when you are accelerating because that is when the joint is under stress. Your vehicle has two axles, each with an inner and an outer joint. My suggestion is to have a competent shop determine which is the bad side and replace the entire axle. The second vibration which occurs at any speed is most likely cause by either a bad tire, or a bent rim.

I would venture to say your exhaust is hitting your frame, or, you may need new motor mounts. The exhaust is what I would lean toward. If you can imagine your exhaust sitting under your vehicle, and the fact that the vehicle has a little age, the motor mounts probably give a little, causing the motor to move slightly on acceleration and deceleration, thus your exhaust is going to move, and may be vibrating on whatever its touching. Good luck.
