If you moved the clutch arm on the shaft, you need to move it back. There are punch marks on the arm and the end of the shaft that line up, when the arm is properly indexed on the shaft. If the clutch cable is good, the pedal height adjusted properly (even with the brake pedal is good), the arm is indexed correctly, and the cable is adjusted correctly, then the clutch should engage and disengage fine. It sounds like to me that the clutch is not disengaging completely. So that means you don't have the cable adjusted properly (or it is stretched and needs replaced), or you have something else, that I mentioned above, out of adjustment.
I doubt that it is because you didn't put something back together correctly. I have heard of some people putting the fiber plate in backwards....but it should have been pretty obvious, that you had it flipped wrong (the pressure plate won't fit down tight on the flywheel, and will have to pulled down by tightening the bolts).
