Yeah, stone counts as roofing for all purposes.

Yep stone works perfectly fine, provided it has enough support from something else.

The big floor tiles will span a surprising distance just supporting each other, especially in a staggered hexagonal arrangement. Once a floor is complete and touching all the walls I can generally get away with just a single central pillar.
