Give it a good wipe around the edges and back near where the power cord goes. They get particularly dusty in that area.

Do you still have the plastic that goes over the screen? you may need that and then it will be the same as when you first got it.

Oh, and don't forget to delete all your porn.

You could just delete your user. It really doesn't matter how you return it, apple will wipe it again.

Boot into the recovery partition (hold cmd+r at boot), wipe the disk with Disk utility.
