I posted this in a different thread, I think it helps answer some of your questions.
I've been trying out different emulators recently. Here is a list of the ones that I've found work best with a gamepad:
To side load them I've been using ES Explorer on my phone to back up the app to apk, then using adb to side load.
To load ROMs, I sideloaded ES file explorer on the fire tv stick, then set up a ftp folder to the fire stick from my windows 7 desktop.
For a gamepad I have the red samarai from gamestop, not the amazon gamepad. I picked a couple up for $7 each.
