Need general drive train expertise

Hey everyone, I'm a rookie member of a team doing research.

On this product's page (http://www.wcproducts.net/wcp-shifter-3cim/), what does it mean by motor pinion select? I see the 11T, etc. down below in the gear ratio charts, but what's the difference between 11Tx2 and 11Tx3?

Also, more general questions:
How do different shifters work?
How does the pneumatics work with the gearbox?
What is spread ratio? Each different spread ratio looks like it has similar overlaps in FPS.

Thanks!
