Yep, those are 2 pole. The common stepping for those is 80 steps/mm. It's pretty obvious where it is in the Marlin Config.

Before you dedicate a lot of time in Marlin, I also recommend Repetier firmware. It's a newer, supported firmware that a lot of people have been transitioning too.

Accelerations are typically in the 1000-4000mm/s^2 range just to give you an idea.
