Query: Great visuals and special fx, but a little hard to follow

I loved the visuals and the DTS sound the movie was encoded with. However I found some of it hard to understand. Who was the old lady who was talking to the princess at the beginning of the movie? If she's a princess, why is she out gallavanting around by herself w/o bodyguards? Who was that one gnome who actually turned out to be good, and did he die at the end? Also, how did the dead unicorn stallion come back to life at the end? Other than that, it was great.
