I recently bought this system and was hoping there might be someone in Montana or even better, Billings that has this system already. I am looking to see if someone would mind helping me through the education process of setting it up and managing it while out on rides. Thank you in advance for your help.

The GEMS is incredibly easy to use. It's like adjusting a six frequency equalizer on a stereo, simple.
You will need a wideband A/F setup to tune your system accurately. Lots of people on SW use the AEM, myself included.

I made a cheat sheet to relate the colors on the GEMS controller to what mode you are in, I can email it to you if interested.

If you are ever in NW MT I'd be more than happy to run you through it.

edit: I attached a screen grab of my cheat sheet, hopefully is legible.

How would you set the gem up in idaho altitude? Sitting at a mile high?
