1- Yes. You should have a speed crank handle with the same socket at the end. Drill is much better, faster.
2- Yes, you have to learn what is that maximum angle between TT and TV, so that you don't damage either.
3- When I unhitch, I ask my daughter to raise the TT with the jack while I put the TV on neutral, allowing the ball to slip past the a-frame receiver. I choke the TT wheels first though. If I'm alone, it's a matter of small fore and aft TV movement to release the ball.
4- I use a small bullseye level, straight on the A-frame on the base of the jack. It's small and does the job fine.
edit: damn, 3 replies by the time I wrote mine.
