Question #1:

Would you want to give coaches formal input on an umpire's evaluation?

Yes, but...

If I were an association officer, I would want to know if we had an umpire who systematically pissed off coaches around a league or conference. That would be a symptom of poor game management skills.

Coach input shouldn't count for much else, as they typically don't know the rules or mechanics of umpiring and so can't legitimately evaluate most of what we want to know.
