You are correct on all counts.
Units in the hex at the time of the fire attack have to make rolls. That means even if they leave because of an event, they will roll. And if they come in from an event, they won't roll.
As for timing, all events are resolved BEFORE play continues, so your other unit will be a Vet when he rolls for his defense. It's like in Europe/Med when a Time Trigger happens and then a unit in the hex being attacked gets a foxhole from a Dig in Action played during the Time Trigger.
E49 is where the Event timing is spelled out, btw.
