Ok this sounds good because it's not exactly duplicate content so it would be better I agree to do the redirect. I downloaded a redirect plugin yesterday that worked pretty good. I noticed that some pages have already redirected people (the tool has an area to see this)
Final question for you, what are your thoughts on that "remove URL" option in Google Webmaster tools? Wasn't sure if that would be better than a 301 redirect for these remaining senseless errors.
Just curious on your thoughts.
Thank you
