I'm in crazy research mode these days, hence the lack of posts. But I have been holding on to this link for a while. It's a radio show out of Canada and addresses the issue of Indian mascots. The show is called ReVision Quest and the episode aired on June 30. It's good. I recommend it for personal information; it would probably work well in the classroom, too.
Also a story I have been meaning to mention that is (somewhat) related: a lacrosse team comprised of young men from the Iroquois nation were denied permission to travel to Manchester, England for the World Lacrosse Championship. The players hold passports from the Iroquois Confederacy and England would not accept these as legitimate travel documents despite assurances from the State Department that the players would be allowed back into the US. In mid-July when this story was breaking, US Representative Dan Maffie (NY) said that if Great Britain refused to allow these players into their country it would be an "international embarrassment." And yet, the UK never did allow the lacrosse players in and I haven't heard all that much about it. Of course Britain's got bigger international embarrassment issues right now.
