Here are the awards, in the order they were presented, and the presenters, to give you an idea of who was there.
Birmingham said that Schellenberg said that Sitting Bull was his favorite role. Schellenberg first played Sitting Bull in Crazy Horse.
Harjo noted that he was amazed by Will Sampson's first words in One Flew Over the Cuckoo's Nest: "Juicy Fruit." Amazed that an Indian said something modern--in this case about chewing gum. He said these words stuck with him and were partially responsible for his making films about modern-day Indians.
Carmelo noted that the CSI: Miami episode has caused some controversy, but she thanked CBS for devoting an hour to a modern-day Indian story. (An episode about an Indian murdering and scalping someone? I'll say it caused some controversy.)
