Rear Pads and Rotors Replacement ?

Hey guys, so I recently changed my front rotors and pads, and the rears started squeaking so it's that next. I know everything is smaller on the rears, but i don't know what differences there are in the process as opposed to the fronts. I've seen just about every thread here about it; most dealing with fronts, but I do know there are some differences. If possible, can someone outline any different parts I might run into, as well as all tools needed ? Thanks a lot guys.

The rears slide in, you don't remove the caliper from the knuckle.

Pull the two pins out (you may need to tap them out from the inside/back with a punch to get them started, then press on the clip and they'll slide out by hand, or wrap the end with a rag and use pliers if they're stuck, and/or use some WD40)
Pull the pad level sensor out carefully. Mine was stuck pretty good, had to use some WD40.
Pull out the spring clip, it will come out fairly easily once the pins are gone. Just a bit of sticky due to brake dust.
Pull out old pads.
Push pistons in for clearance just like the fronts.
Grease the back of your new pads, slide them in.
Replace clip.
Replace pins.

Avoid getting WD40 on the rotors and pads.
