Hi, my ep3 is driving me nuts please help!

Last year i replaced my clutch but didn't touch the throwout bearing and pilot bearing.
at that time it was hard shifting, when accelerating hard at high rpm the car would not go to 2nd without grinding.
Ive solved this then by adjusting my clutch pedal for max throw (this sortof solved my problem als the engagement point was still at the floor but enough to drive without grinding gears)

Last week i started my car and the clutch wasn't disengaging fully?! car wants to go forward when putting in gear.
2 days later it was somewhat better.. but now when starting cold and releasing clutch pedal in neutral the car vibrates.
It does this for 3 minutes or so till its a little bit warmer and when driving there is a fast vibration at around 2k rpm in the car.

What is going on please help!
