I have the 24-105 f/4, 50 f/1.4, and 85 f/1.8. I recommend all three.
The 24-105 f/4 is not a good indoor or low light lens -- it's just not fast enough. I have taken a lot of landscape shots with it on a tripod and they have turned out very well. The shots of your daughter will be tough because of its speed. That said, as a general purpose lens, it is sharp, it has great coverage, and it has IS. I love it.
The 50 f/1.4 is great for the indoor/low light shots. It has a nice halation at 1.4, which I really enjoy.
The 85 f/1.8 is a nice light lens. I have taken indoor shots at a zoo, landscapes, and portraits. All have come out well. It focuses very quickly. The one drawback is CA: it fringes a lot.
Regardless of the focal length, you will need at least one fast lens for shots of your daughter, the museum, and the aquarium.
