3. Remove the glass, and replace sunroof cables and cover plate
So what is exactly the right method, and exactly what parts (MB part #?) do I need for the job? mine opens about 2" or so and then the motor spins freely and nothing grabs. Thankfully it will close though.

When I was having problems with the sunroof in my W210 I was able to "help" it to open all the way by pushing on it while holding the switch in the open position. That revealed the two cable hold-down brackets, which in my car had apparently been replaced with the updated part that uses 2 screws but they only put one in for some reason.
I put a second screw in each bracket and since then the roof opens and closes all the way as designed.
The brackets keep the cables from popping out of their track so if they are not properly held down the roof only opens part of the way before the cables pop and the roof panel stops moving. I suggest you try opening the roof all the way with a little "help" and look at these brackets to see if they have one or two screw holes. If they only have one, get the updated part from the dealer and install it with 2 screws on each one...see if that helps.
