I would take a look at the intermediate driveshaft bearing and the guibos. If you have the means to get the car on some jackstands, you can check these yourself. Look for cracked rubber. You can examine those motor mounts while you're under there.

As far as changing any of them, they are all pretty tough jobs without a lift.
