Hey southpaw, I'd definitely agree that for someone in your situation, getting involved in opposition scouting might be the most useful role. Helping scout our next opponents, figuring out what they do well/poorly, how best to attack them, etc, is probably to most transferable skill one can take from being involved in the NT, since it's pretty similar to how you'd want to plan for league matches. Of course, the levels of skills are different, but I don't think that makes much of a difference--teams still have their relative strengths and weaknesses, and finding those and figuring out how best to exploit them is pretty valuable.
As for the offsite, there's a thread pinned to the top of the bb-usa forum (NT news & info, this one, I think:
