dash repair

Ok, well a while ago, I had drilled a hole in the dash of my 94 Caprice Classic, where the ignition key goes (that empty area facing you).. I put a button to start my car as I had a dead alarm that wouldn't let me directly start the car, and had a remote start installed..

I finally got that all fixed up, and dead alarm gone.. But now I have this half-inch hole in my dash.. Any way to fix it up to the point it looks like there was never a hole? I regret taking a dremel to it..

Also, where the headlight switch is, the black plastic area, the LED for the alarm was removed too, and I have a hole there too..

My car has neon lights installed (before I owned it), and I was thinking about maybe putting an LED indicator in one of the holes, so it atleast has some use...
