Lee,
While I'm getting up to speed on the two articles you mentioned, have
you read the following?

American Indian mtDNA and Y Chromosome Genetic Data: A Comprehensive
Report of their Use in Migration and Other Anthropological Studies by
Peter N. Jones (July 31, 2004)

http://www.iiirm.org/publications/Articles%20Reports%20Papers/Genetics%20and%20Biotechnology/Jones%20DNA.pdf

It seems like a fairly comprehensive summary.
