You will have to "rebuild" the serpentine belt system-buy a new lever (028-903-308G), tensioner (028-903-315R), two bushings (028-903-310) and two rubbers (028-903-313). You should also replace the alternator pulley with a clutched one off a TDI (028-903-119AA), this really extends the life of these parts. You can source these parts aftermarket if you shop around long enough, saves big $$$.
As for the clutch noise I have not heard of that type of release bearing making noise (tdi trans yes, but not the 020 trans)-could it be something loose in the clutch/flywheel? The release bearing is inside the green cover at the end of the transmission, easy to change/inspect if needed and cheap.
