I can only really speak to your first point. When imported my existing library, I did it using Sonarr/Radarr as applicable. They have a manual import method, here’s a description of Sonarr’s.
Unfortunately that’ll probably work best if they’re formatted in a way Sonarr can readily recognize, something like /Season ##/S##E## - .ext
. It may take a little work to get there, I found a program called mmv which helps out a lot. It allows you to move files that match a pattern, capture parts of pattern, and use that captured part to name the output file. That allowed me for format entire seasons at a time, but that method does rely on most files having similar names to begin with.
It does get disabled to the Quarterback, however I believe the Head Coach can flip between channels to talk to Offensive and/or Defensive coordinators during the play.
