Throw the gerbers into an online viewer and you'll be able to figure out layer count, dimensions, and some other info. For board thickness, that'll more depend on what the fab is willing to do if it's >2 layers, as well as what the space allotment in the blaster files themselves is. Thicker should be better unless otherwise limited.
