3 - Thread cleaning
Don't forget some cutting compound also, especially if you intend using power tools.
4 - Tapping when confined
This can also be done for tapping, where you reduce the sides of an old socket to hold the Tap firmly (squash in a vice).
5 - Use clutch screw control
A good way to reduce the Tap or Die from binding on the thread is to use the screw control clutch on a drill, this will prevent you putting too much torque through the Tap or Die. Just reverse the drill a few turns and go again.
