Did I get it right?

Here is the sitch.

NFHS: Player A1 drives to the hoop and gets fouled by B1. This makes 5 fouls for B1. Player A1 then taunts B1 and picks up a technical for his actions. This technical makes 5 personal fouls for A1. I directed both players to leave the game after reporting of the fouls. I then instructed Coach A that A1's replacement would be the shooter for the original foul. Coach had a preference for A1 to shoot his own free throws. I instructed him that this player is now disqualified and is instructed to leave the game.

Did I get this right? or does he have to shoot his own foul shots first?
