Bontrager crank question...

Hi.
I've managed to get a cheap Bontrager crank set(BR3 JAH, 9 speed) in my length.

It has ISIS Drive on it. Does that mean it needs an Isis drive bottom bracket?
It's a double. What model/size(length) bb should I go for?

What model Shimano would this model of crank be comparable with?

Thanks for your help, Paul

Yup, gotta go with an ISIS bottom bracket.
