The things you list are all good and the list is certainly not complete. Some additions might be:
Join and participate in IDPA
Find an instructor that has been one for some time and develop a mentor relationship both in class and outside. Ask them what their assessment of skills is.
There have been some great shooters that make lousy instructors, and vice-verse. Being an instructor is more that shooting well. Communication, transfer of knowledge, presentation, and instructor confidence is necessary as well. Develop the teacher portion as she develops the shooter.
Take private shooting lessons from a qualified instructor and observe their interaction with you.
Range time is good, but practicing bad habits just leads to ingrained bad habits. Learn good habits first.
Contract with an instructor and have them take a class from your daughter and provide honest and frank feedback.
I too am a father and know what you face. Hope all works out well.
