Drilling in fiberglass is amazingly easy. I'm not saying don't be careful but it's not at all difficult to do. What's more important is to make sure you get the hole the right size. That is, don't undersize the hole and then "force" the screw in. You can easily break the head off of screws when screwing them into fiberglass if the screw is of the cheap "chinese" variety. I speak from experience. I had to move my cowl mounted mirror over 1/2 inch to cover up a screw that I broke off in the cowl. I'd even suggest replacing the screw that comes with your mirror with a stainless steel one if you can find one at your local hardware store.
