RM,
If she is interested in doing Web Animations, then Macormedia Flash and Flash Professional are great tools.
There are more indepth software like Maya, 3D Studio Max, and Lightwave which do more cutting edge 3d graphics. But they are very pricey, and usually reserved for professionals.
If she wants to do gif animations, then Fireworks and Adobe Image Ready are good programs.
I use the whole Macromedia Studio, and I work with Flash, so speaking from experience, they are great products.
