Woo hoo!   I have fixed my issues.  It turns out some of the stored procedures didn't get upgraded like they should have.  I think this might have happened in a previous upgrade.  I generated a script from a clean install of the database for a create/alter for all core stored procedures.  After I ran it I went throught the upgrade again and the module defintions error was fixed.  I was still receiving the error on the skins and langugages page.  After doing some debugging I figured out it was trying to insert new module definitions for these even though old definitions already existed with the same name....so this was causing an error.  I deleted the rows for 'languages' and 'skins' from the moduledefinitions table, re-ran the stored procedure script, did the upgrade again and voila I now have a working site.  I hope this helps.

By the way I'm probably the last person to figure this out but to debug the upgrade I added code to the '\Library\Services\Upgrade\Upgrade.vb'....recompiled the library project and added the DotNetNuke.dll to the website bin folder.  Then re-ran the upgrade with my new debug code.
