I line the tin with electrical tape, two layers. Make sure you also cut the leads of the on-board components down as flush to the board as you can. Then, put a couple of layers of electrical tape on the bottom of the board as well.
Start by using some masking tape around the perimeter of the tin. I use the actual securing nuts for the jacks, pot, and switch to use a guide to mark where the holes will go. Use an awl to punch a small starter hole (the masking tape will prohibit the awl from "running" and creating a nice scratch in the paint). Remove the tape and start drilling. Use a small bit for the first hole, and then go every other bit size until you get to correct size hole.
Take your time and you'll get a nice clean opening.
