First, I also have a problem w/ a coach taking a position behind the plate in the same tourney where his team is participating. This is not the place to be scouting an opposing pitcher's command of the strike zone.

Second, I have a problem with a rule modification unless it was clearly stated in the local ground rules. Even then, I would politely request an explanation from league officials as to how this 12-ft trend line came to be in place. State that it is a new situation and you just want some info.

Third, and take this lightly, read the comments one of the league directors made to you and how you responded to those comments. He may have said that just to shrug you away, hoping you would let it go. Try to find out more about the situation and avoid any rash judgement about those people. Step away from this issue for a while. It should be clear that most "baseball" people acknowledge the usefulness of NFHS rulebook, even as poorly written as it may be.

Fourth, I like DG's comment about warming up outside the field, or perhaps off the right or left field fence line, if it is possible w/out delay. Otherwise I would have the bats ready for the players to warmup while the defense is taking the field. I would then encourage them to rest in the dugout until it is their turn to bat.
