Ebayref - welcome to the forum, and good question. The first thing you did right was get together with your partner and discuss what happened, and what you're going to do next. In the heat of battle, sometimes things get overlooked, and this discussion time is a good place to calm down and get things right. As far as NFHS, A1 does need to be replaced first, before anything else happens. Then, fouls are penalized in the order they occured, so the intentional foul gets shot first (2 shots), with A6 shooting with the lane cleared. Next, any member of B shoots the T, with the ball then taken out at the division line by B. In NCAAW, the T is penalized first, then you go to Point of Interuption. First, sub in for disqualified A1, B shoots the T, then A6 shoots the intentional, and A gets the ball out at the spot closest to the foul.
Oh, and when did we start getting formal, like "Mr. Jurrasic Referee"? Is he really that old?
