You can use the stuff underwater just fine (it sets and cures underwater within a half hour or so), and that'd be the easiest anyway. The epoxy doesn't really stick very well, so don't think of it as "gluing" the rocks together really. The trick is to get the rocks to "nest" together, and then use the epoxy to lock them in place. If you have a bunch of flat, non jagged rocks, this method doesn't really work - but if you have jagged rocks with lots of nook and crannies then you can usually find a way to wedge the rocks together and then put a blob of epoxy in a hidden place to keep them from coming apart. The epoxy sort of acts like a "keystone" - the single piece that locks them all together.
If you get the D&D brand epoxy, I'd recommend following their instructions about "working" the epoxy in some water OUTSIDE of your tank before putting it in the tank. While the D&D brand is about the stickiest stuff I've found, it really gives off a cloudy residue if you overwork it in the tank. It doesn't hurt anything... it just kind of clouds things up for a few hours and makes you clean out your skimmer more than normal. The other brands don't cloud up as much, but aren't as sticky either.
Once you start working with the stuff, you'll get the hang of it - but just don't expect it to "glue" your rocks together.
(Personally... I'd find another home for that fist-sized snail. He's going to be nothing but trouble if you go the coral route.)
