Yes. It does not make a difference whether is is the conventional, slotted or drilled rotors. They can all be machined in a brake lathe with the same accurate result.

NO! No...no...no...! Do not put any grease on your brake discs, copper grease is used to put on the 'back' of the brake pads (not the part of the pad that comes into contact with the disc).
Typically integral parking brakes are on rear disc braking systems. By activating the parking brake it adjusts the discs on the rear brakes. While the front discs are self adjusting, on the integral systems the rear discs are not self adjusting, thus the need for the integral parking brake system.
Only if they are defective.
The caliper might be sticking
there are factory rivets which have to be drilled out
The friction of braking makes brake drums and discs very hot.
