1) Smooth it. Scotchbrite wheel. As said previously, it probably won't make a difference on the tail but the same features WILL make a difference on the wing. Use it for practice.
2) Follow the directions. The need for the empty holes for fasteners depends on how good you are with fiberglass. I have the minimum number of fasteners in my fairing. Dimpling the assembly at the end and installing rivets is not a problem.
