MMM & Spektrum users, I require your council..

I think I have my EPA set somewhere between 110 and 125 (whatever max is).
Yes, you will likely have to fiddle with the arming time. I had to adjust mine slightly.
Throttle channel reversing is almost a hit or miss depending on how you wired your motor, so its likely you'll have to do that.
Binding can be difficulat at times. Sometimes mine take right off the bat, other times its 4 or 5 tries.

Other items you asked about - I dont know for sure how I have them set.
