As to the FSR, have her do the walk through. After she releases the ball, she should keep her right foot off the ground until the ball is returned to her by the catcher.
The video I posted shows the pitcher keeping her right foot off the ground until the ball hits the catchers mitt. Your DD should keep the right foot off the ground until the catcher throws it back to her. The first time your DD tries it, she'll fall forward. She'll learn to keep her upper body back.
