Did I mess this one up?

5 seconds has nothing to do with it. Once it's determined that Team B is not going to properly inbound the ball, you whistle the violation.

2) By that logic, say B2 who now has the ball gets fouled. Pretty bad to penalize team A for fouling someone when the ball wasn't even live and technically there was no team control. Just doesn't make sense to me

It makes no difference whether it makes any sense to you or not. The current 3 man mechanics on not switching for a foul in the BC makes no sense to me but I still follow them. Read the case book play and call it properly.
