Take the power to the MPG from your computer or breakout board , put the A and B channels of the MPG to two inputs, go into Machs Ports and Pins then the Encoder tab, set the port and pin numbers you have used and thats it except for calibrating. To calibrate go the Function Configs menu then Calibrate MPG, remember to save before you exit.

 If you press the Tab key a flyout screen will appear which will allow control of the MPG, I prefer to have physical switches on the panel to change between MPG and JOG, also to change axis and also to change between Velocity mode and MultiStep mode.

Yes, I have 3 buttons on the Mill and two  on the lathe and the pendant I have for the mill uses a rotary switch. Just have to have enough spare inputs.

I have never used it but lots do and they say it works well when set up correctly, that is if you are using the parallel port.
