Villian is a complete unknown.

What does action like this usually mean, and do you make the call?

could be a lot of things...I've seen bottom pair do it. I think it usually isn't a sign of big strength though, so I'd gamble with the 17 already in the pot. after all you're leading any pair below QQ...

With no read I'm gamblin here baby.

He cold called a raise and re-raise from BB. What's his range for doing this? Average NL50SH: TT+, AQs, AK? What would you change for average?

In any case, its hard to come up with a range that says you shouldn't gamble here given the pot so I'd go with....what Benny said.
