I've found a job again so I'm back, but I think the clutch in my R56 JCW is going out a bit earlier than I hoped. Symptoms include audible clatter/squeak unless the pedal is held at a specific spot in its travel, recently joined by an audible buzz/squeak at speed which a tiny touch on the pedal will quiet (often for good). Shifts are getting very balky, and getting it into first or reverse can be nearly impossible with the engine running. Can creep in gear as well. It's gotten a lot worse just in the last couple of days, so I have two questions:

1. Is the whole clutch going to have to be replaced or is there a failing part like a throwout bearing that can be replaced individually? (Don't think I can afford the upgraded clutch I wanted yet and didn't want to have to buy another stock clutch before then.)
2. Is there something that can be adjusted as a stopgap to keep the car driveable until I can get it in at a shop?
