What is causing this terrible grinding/groaning noise when I come to a slow stop sometimes? (but not always!)

Is it normal for the car to vibrate on the BITE when no gas is given in a manual transmission?

More than likely, the clutch just isn't broken in yet (or bedded, for that matter). You need to not ride the clutch at all, don't over heat it, and don't try not to prolong it's usage during this ...
