different manufacturer, actually. The thin coat is probably what made it work.

Must depend on the foam. If there's enough air in there for the water in the glue to evaporate into then it will dry. Very dense or closely fitting foam will prevent the glue from drying.

Elmer's glue (PVA) doesn't dry when used in foam to foam gluing.

There's a neat Instructable out there which uses spray paint to disolve foam in order to produce a fake stone signboard. In the Instructable, letters were masked off with card, causing them to stay raised, while the surrounding area was eaten into. I don't recall what it was titled, but you might find it by running a search.

At the hardware store (where you get the foam) you will find the correct adhesive to glue the foam pieces together (and to glue stuff to the foam) without it dissolving. It comes in a 300mL or 825mL tube, and you'll also need a caulking gun to use that glue. Then, yes, you can use a dremel or any other tool capable of cutting foam (pretty much anything) to shape it into the form you want.

Some of the foam will 'dissolve" if you use spray paint so test before you spray. This dissolving cab be used to good effect if you need irregular surfaces like bolders.
