help with new league

[tidefanintenn]

Hey guys this is my first post eventhough I follow all of the other things on here. I umpire Dixie youth and Dixie Boys (9-10;11-12 & 13-14). I have been asked to take over as UIC over a league in a nearby town. The President wants me to clean up his league with the way the coaches act on the field. His umpires have also been below par the last few years and would not enforce many of the rules. Mostly because they did not know them. I would like some suggestions on how to handle these coaches next year. I am known well in this area as an umpire that knows the Dixie Youth Rule book and have no problems enforcing them. I do not want to seem like a hard a$$ when I step on the field next year, but due to the lax rules enforcement I know I will be a little because I do enforce. Any help from you guys.
