Should I be using fiberglass mat (like woven fiberglass that looks like white carbon fiber) or should it be the cloth (like ones that have random fibers sticking everyway) for my sub box? Also what's the major benifit of wet sanding? If it's worth the effort how do I do it? My grandfather's a boat guru and he's done tons of it but I've never paid much attention to how he does it. Thanks

Yes.
I like to stary the buildup with a layer of chop mat (the random 'cloth) or two, and then build things up with alternating layers of cloth (white CF looking stuff) and chop mat. It makes an amazingly strong structure pretty quickly, especially if the box has curves and compound corners.

Does anyone know about the wet sanding? I've read that it's a good way to get a real smooth finish but will a good dry sanding do fine to get that glassey finish that I'm lookin for (along with a good paint and laquor coat)?

Wehn you say wet sanding, are you talking about after you have bondoed and sanded down the surface, primed and painted it? Ive seen great results with just the basic steps, not sure if wet sanding is necessary, but who knows?  ------------- Im a fiberglass whore!!

Wet sanding is the very very very last thing you do. It comes after you build the box, sand the box, bondo the box, sand the box, bondo the box, sand the box, prime the box, sand the box, paint the box, paint the box, sand the box, and paint the box. Use it if you need a competition grade mirror shine. Otherwise, spend the time sanding the bondo and high-build primer until it's like a baby's butt. Wet sanding is only used to remove the orange-peel effect that you get when you spray a finish, which is pretty minor on most of the well sanded boxes I've done.
