The location used to film the mall scenes is South Bay Galleria in Redondo Beach.
During the scene where Louis and Twitty are pounding on the door of Shoe Circus and the mall cop first catches them, you can see a sign for the arcade, Funtasia, in the background. This is a call back from the episode "Easy Way" (season 1, episode 10) when Louis misses out on his friends and family going to the grand opening of Funtasia.
The song that is played in the fashion show is the same song that is used in the That's So Raven (2003) episode "Party Animal", in the scene where when Raven is modeling the snake.
