I can't clearly remember my psychics class, But I think I'd fall a bit faster, as the movement through the pipe is considerable as well.
They used crystal balls instead of magnets in my psychics class :)
I don't think the spinning should have any effect on the speed. Only the vertical movement would create eddy currents. It could be he does it to keep the magnet stable as it falls (like spin on a football).
In the last drop he doesn't spin it and it seems to fall at the same speed, it also wobbles and hits the side, so I think you're right
No. Because copper isn't ferromagnetic, it will not be magnetized by the magnet, and consequently the magnet and the copper will not be attracted to each other. (In fact copper is diamagnetic, so it will actually slightly repel.)

Judging entirely by the name, that sounds awesome :D What do you do all day?
A lot of reading, plumbing, and electrical work. But when things are running smoothly, we grow complex oxide crystals using pulsed laser deposition and then measure their magnetism with SQUIDs (superconducting quantum interference devices).
So what would happen, minus the spin - straight through at roughly G?
