If you need more holes, buy some rubber grommets and a hole cutter. Super easy to do.
The hole cutter you want is either a knockout punch or a stepped drill bit. You really shouldn't try to use a stepped bit with a hand drill. Something like this: http://smile.amazon.com/Greenlee-7211BB-1-Slug-Buster-Knockout-8-Inch/dp/B0018LC8WI Be aware that the edges from that are super sharp. You will need some emery cloth or sandpaper even if you're going to use grommets.
