...My question is, why is the coma roughly spherical if it's shooting away from some vent?
I think a lot of people would like to know that, Joe. I'm surprised that there has not been a bunch of discussion about that very topic on the various professional web sites I frequent or the lists I'm on to which professional astronomers subscribe. One would think that if the eruption was caused by an impact the result would have been a very asymmetrical cloud similar to the one created by the NASA impactor hitting Tempel 1. And, like you, I can't imagine how the vent scenario would explain what we see either. To quote the king of Siam: "Is a puzzlement." patrick :)
