Yes, I would put new Camshaft , Lifters and bearings. Remember Injector rockers and bearing cap bolts needs to be replaced ., total of 18 bolts .Little more progress. All lobes, lifters, and bearings are badly worn except for the rear most lobe and lifter, number 8, which has no visible wear at all. I did a little dumb dumb and as a result I'm putting a new head gasket and head bolts in. At 350k kms it's probably a good idea to do while it's this easy anyway with how inexpensive the parts are.
I can post a picture with the fork off later today. What you see there is just an extra support to pivot on but the usual pivot ball that you mention is also behind there. If I were to remove that support and just leave the ball the fork would sit in the same position.What is the part visible from behind the clutch fork's pivot point? All of the pivots I've used on TDI's is a simple button that screws into the bellhousing and the retaining spring snaps over to hold the fork in place. It appears that part may be holding the clutch out further than it should.
I think the clutch pedal should go full range to the floor. Hydraulics that reach their limit will spike pressure, often disastrously.
