I'm getting a vibration that is felt mostly in the clutch pedal and gets stronger the higher the rpm's go. I can feel it very slightly in the shifter, but I think it's just the vibration moving up the tranny. Also, when sitting at a light, I can hear(very slightly) what sounds like a rubbing noise, but when the clutch is pressed in, it stops. I'm thinking that the noise and vibration are clutch related. What do you think?

Not related to clutch: When moving the shifter to line up with 1&2 or 5&6 it will spring back to line with 3&4. What is it that makes it spring back? Because mine won't spring back from lining it with 5&6.

 

The T/O bearing will make that noise you describe and the spring in the shifter is what help's center the shifter... not sure if ti's adjustable..
