The rear rotors are a piece of cake to replace. Don't worry about the e-brake inside - it doesn't really complicate anything. You might have to adjust it slightly if it rubs too tight against the new rotor, but that is simple to do.

The front rotors are much more complicated as they are integrated into the bearing/hub assembly. They don't just pop off like most cars. See this thread

I've had BAD experiences with Raybestos reman calipers. The quality seemed really sloppy to me. Rubber seals were put on crooked, bleeder screw threads were worn, and a couple of them rusted horribly and seized within a year. I've had much less trouble with autozone/advance house brands and Beck Arnley.
