Don't bother to clean up the underside of the deck around the cockpit opening until you get the coaming in place. You'll be cutting and rounding the coaming riser anyway, and you might as well only work that once. It's best to keep the deck thick in this area rather than sanding it down twice.

The cyanoacrylate glue is sometimes referred to as "CA" and it's just a thicker version of superglue. Best bet is to stop by a full service hobby shop and pick some up. There is also a spray "zip kicker" that sets the glue just about instantly. Brands are many - the manufacturers seem to be willing to private label for every little ma and pa shop.

You can also use hot glue on every third or fourth 2" riser piece with Titebond on the rest, using tape to keep things from sliding down. The hot glued pieces set up pretty quick and keep the rest of the pieces in alignment. You are also not going to stick yourself to the boat like you might with the CA.
