Ok...you blew the call. You know it now, but you went with what you thought was right at the time. Bet you won't ever miss that call again!
Both ejections sound alright to me...don't have quite enough detail to comment about the first coach, but "You suck, Blue" definitely earns a tour of the parking lot.
I'm glad to hear the UIC backed you up on the forfeit - I've been around situations when that did not happen.
Chalk it up as a learning situation...As far as continued study of the rules, I like to focus on some of the rules concerning stuff that you don't see that often. That seems to be where a lot of umpires get themselves into trouble by trying to make up rulings on the spot instead of knowing the rule and enforcing it correctly.
