Hmm. I would start with the Motor mounts. Check to see if the rubber on the mounts are still good.
Then start checking for the vacuum leak. But on the clutch ... hmm.
Is the vibration only when the car is moving? And does it become even worst when you accelerate?
If it's when you accelerate, could be a few things. New to balance your tires, need an alignment, bad bearing (as you stated) or bad tie-rods.
