Canada, I will be kind, since you purport to still wanting to learn.

1) You don't ever "follow a coach" to get to him. Make him come to you. A coach wants to talk to you, make eye contact and don't move. If he still doesn't get it, motion him towards you.
2) If a coach begins to yell at you accross the diamond. Call "time", if it's not already called, beckon the coach to join you. "Coach, come here". Now, when he is within normal conversational distance tell him. "coach, i don't appreciate being yelled at accross the diamond. If you want to talk to me, this is how we do it". The ball is in his court now. The next time he yells at you from afar, eject him from afar.
