1) it's rather noisy until the pedal is depressed
Bearing on its way out (usually comes with the clutch kit)
2) I get clutch judder if I try and pull away perfectly, the whole car shakes!
Assuming standard dual mass fly its starting to go - see DarrenB he destroyed his
3) sometimes I have to double clutch when slowing down and coming to a stop to get it into 2nd or 1st
More like gearbox - oil change first - helped a lot of members
4) clutch pedal doesn't always come all the way up, however this could just be the spring on the pedal
Usually slave cylinder - replace slave cylinder and add a braided hose - new fluid jobs a good un - he does a kit
If your replacing the clutch do this after as it may be a weak spring but I'd expect it to be the cylinder.
5) again to do with number 4, the pedal has a fair amount of play in it and has to be depressed about an inch before it actually feels like it works the clutch
As 4 - also a worn clutch plate will increase travel.
