Welcome to Saddos.

I can't help you with how that gym is, but am sure one of our fellow training sectioners will step in with that.

As for the size, I wouldn't worry too much. You'll be spending most of your time getting in top condition and no sense worrying about things you have little control over. As for being short-sighted, again, dont worry, you'll fit right in! A lot of trainers tend to be that also.

Again, welcome.
