1. Are you sure that the rear engine seal was good? And did you use sealer on the threads of the bolts which hold the flywheel to the crank? Sounds like a clutch disk with oil contamination. I just went through that on my '65 Mustang. The bolts which hold the flywheel to the crank seeped oil. Had to replace everything and use sealer on the bolts.
2. This is most often caused by a bad pressure plate. It isn't engaging the clutch disk evenly. Unfortunately, new only means new, it doesn't mean it will operate correctly. I have installed a few clutch assemblies only to have to exchange and reinstall - it's a bummer.
3. Clutch chatter happens on high performance clutches. Give it some time it may need a longer brake in period. Try not to beat on the car too much while you are still in the break in period. Also you may want to invest in a adjustiable clutch quadrant.
