Instead of playing uber accoustigeek ion this one and suggest you go out and buy some expensive meters, etc. I'm hopefully going to suggest a few things that in practice should work for your purposes.
The first question I might hve though is are you interested in the noise floor of the room, or the recordings you plan on making in said room. The difference is that the room will have one number, on top of which will be any microphone self-noise, noise from cables, mic pres, fluctuations in electrical signals your equipment may receive, potential noise such as ground loop hum, etc.
I'd suggest you set up your recording equipment and then make some recordings, sans eq, compression, etc. to somewhere around -9db and peaking to -3. Make sure to leave several pauses where you stepo back from the microphone and that will be your effective noise floor.
For the record, this is something that tends to work in practice and wouldn't be what an accoustician might recommend.
If you are looking to get specifics on the noise floor, that might lead you to developing accoustic solutions, and you happen to have an iPhone, Studio Six has a suite of tools that are very inexpensive and do quite a nice job.
