As a teacher I had many contacts with CA, AZ Indians, Indian schools. I did not meet Pimas, but based on my expereinces I would recommend a somehow different approach.
The best way to help - to visit them, to talk with them and then to decide how to help. I do not think that any tv program, article etc. could tell you how THEY feel, what THEY think, what THEY need. If you do not have opportunity to go there try to contact with one of their leaders, teachers. There have been so many misguided educational and other program forced on Indians - they do not really trust in strangers, outsiders. If they see/hear something new they will ask their own teachers, leaders, doctors what to do.
I agree they need teachers who can interpret health issues. Teachers who know their language, thoughts, feelings.
