I'll bite.

1) BR has no right to interfere with F3, whether already retired or not. Does it or should it matter if BR knew she was out on IFF; she interfered, period. No jeopardy attached to BR if call is changed or delayed. If the IFF is the correct call, and is made retroactively, anything that isn't caused by jeopardy due to the changed or delayed call is appropriate.

2. My opinion, do the best you can. And you did what the manual tells you to do. If the teams want you to know what play they are calling or who is covering, they need to tell you, because they are intentionally making it as obscure as possible to fool the offense. Or, they can pay for three umpires that can adequately cover their intended obfuscation.

3. Someone needs to be ejected at that point. (As KJ suggests, possibly before the warning, but you chose that manner of handling.) But, your dilemma is who to eject, because you don't actually know who said it. The good news is NCAA 4.4 covers your situation, because the Head Coach is accountable for (among other things) the team's conduct and ALL communication with the umpire no matter what team personnel actually says (or initiates) it. So, my handling would be to 1) call time, 2) go directly to that team's head coach and tell him/her in as calm a manner as possible that he/she is either a) giving up the guilty party, who will be ejected, or b) he/she is ejected as the one person accountable no matter who actually said it. But that's just me.
