Is there anyway to turn off all those interim messages, so you only get the finished training message. I could turn off events completely, but that would stop all events of any kind.

I don't think so. But it's a something you can suggest on that suggestions forum. I think it's a great idea, those are kinda bothering me too.

and if it could just say how many points you got total, that would be great too

Good thinking, i will include your idea in my suggestions.
