As for drilling the holes, I am no expert but one way to prevent chipping the paint is to use masking tape over the hole you'll be drilling and perhaps using a heat-gun to heat up (melt) the paint somewhat before drilling.
^Thats what I have heard aswell.. To add to that make sure you use some felt washers where the hardware meets the body to help keep it from starting to rust.
There was an Schassis guy here on NICO a couple months ago that used a neoprene washer.
