I hope it's held in by clips. I was going to remove the door panle but I'll just wait until the part come in to see how it should go in...I can't tell from the drawing if the switch bezel is separate, but I would say probably. As for removing the old one, I'm sure it's held on by clips. Just pull up gently and it should come off.
