Piney,

I found this link helpful in deciphering fire AND burglary resistance ratings:

http://www.klsecurity.com/ul_fire_rating.htm

It's important to note that fire safe ratings and burglary resistance ratings are different, and not every safe (maybe not even most safes) achieve protection against both. In other words, a safe that protects your guns against a fire may be not much deterrence to a burglar with a few tools.

As far as the second floor goes -- I would get a professional engineer/reputable housing contractor to advise me on that one. Even if the floor joists are up to snuff, the underlayment (usually a layer or two of 3/4" plywood) may need some reinforcing -- I know of one installation where 2x6's were laid across the floor to provide support between the joists.

Good luck, and post back when you figure it out.
