A standard hole saw has a drill bit on which you attach the hole saw teeth. The drill bit is used to center your hole, it also protudes further out than the saw. The drill bit will penetrate the inside surface well before the hole is complete. You simple go to the inside of the boat and place the drill bit in the hole and start sawing.

Do not use a regular hole saw. It will chip the gel coat. Goto Home Depot and get a 1" Diamond hole saw. It cuts like a hot knife through butter. I use this when I cut my holes for my new ballast system.

Don't really see a reason to use expoxy or sealant on the thru hulls, they don't do it at the mfg level. if you ever change them out it will be a B&tch to get them out using the 3m 4200 or 5200. MY .02 They shouled be well above the water line so splahing and rain water should not seep in.
