If you want a response based on the law of a specific state, you need to post in that state's forum, in your case fora.
On the second query, that's a "limitation of damages" clause; e.g. if my annual rent was $60, it would attempt to limit my damages to X times $60 even if the custodian was negligent. So, if there was a mysterious disappearance of a $10,000 diamond from my box and I could prove you were negligent, my maximum damages would still be 5 X $60 or $300.
That language was written for a different world, one where customers were dumb enough to believe they were bound by such terms. I doubt seriously that any court in the land would enforce it.
