Do we have back court? I have received two different answers from two different veterans, and the rule book is confusing me.

Once the throw-end has ended, all backcourt rules apply. The key here is to ask "where is A3's location while airborne?". If no part of him is in the backcourt when he catches the ball, he's still in the frontcourt. When he lands in the backcourt with the ball, he has violated. See rule 4-35 Art 3.
