That's true, but BBs have a nasty tendency to collect water. If you
don't grease those threads, they will soon be firmly held there by rust.
Threaded fasterners should be greased to prevent corrosion and to allow
proper tightening. Torque specs assume a greased thread.

Locktite is not needed with BBs, as a general rule. But heat will allow
the seperation of locktited parts.

Yes, but it's also important for proper alignment of the bearing races.
Improperly faced headtubes and BBs will result in a shorter life, if not
better function.
