From looking at the data sheets, it's going to be a bit more of a project than just "hooking it up". At a minimum you'll need to have a small micro to decode the dual PWM outputs, and they (AD) have a data sheet describing the use of a Parallax (...)

Ncm is the metric measure for torque, imperial is ft/lb's hence 5Ncm is the the amount of torque required before the gear will 'slip', 2.5Ncm before it will engage again. the difference is the hysterisis. one would assume that Lego has a range of (...) (25 years ago, 16-Oct-00, to lugnet.robotics)

(...) I think Ncm is Newtons per centimeter, but I can't remember how a Newton is defined. So, if you're spinning the drive shaft, and the counter force on the gear teeth is less than 2.5 Ncm, you're fine. If the counter force on the gear teeth is (...) (25 years ago, 16-Oct-00, to lugnet.robotics)
