It sounds like your D has already decided to focus on MT. I was going to suggest trying to decide between Dance or MT. Having just gone through auditions with a dance major myself. She may very likely be asked what her goals are in the interview portion of an audition and if dance performance is not her main goal it may hurt her chances of getting in as a dance major. My only other suggestions would be to visit and observe if at all possible, as soon as possible. We lived too far away to visit schools before applying. Also have your D keep an open mind about locations, etc. My child had some quite rigid thoughts that turned out a little different in the end. You truly have to weigh what each program has to offer and what type of training/academics you want. My D thought she only wanted to be in NYC, which is where she is headed; but her dream school changed in the end after seeing each program and as it turns out her dream school is not in NYC. So when she got accepted there she really had no idea how big of a deal it was until we visited in April! (She was still stuck on the original dream school, which is not the best place for her anyway). I would be hesitant to rule out top programs. We had no idea where our D would land. She ended up getting into one Top school, and wait-listed at 2 others. And rejected from many that we thought may be second tier schools. As I was told, cast your net broad and wide. The competition is tough and the whole process makes no sense. You just have to put yourself out there and see what feels like the right place for you.
Best wishes!
