So CDW ultimately had to return and exchange my purchase to correct the information in the agreement that was including the purchasing agent. HOWEVER, the user management tool still reflects the other person's name, CDW says Microsoft must have associated that person's name with my email, and Microsoft says CDW has to fix it. CDW has reached out to Microsoft, and I have gotten a ticket into Microsoft, they said that I would be contacted by email as to the status within 2 days and within 6 days it would be resolved. A week later I got the email confirming that the ticket was lodged, but never got a resolution.
Right about the time CDW processed the exchange, Microsoft wrote to say that my issue behind why where I could not manage benifets because of errors was intermittent and that I should try again. I had tried morning, noon, night, weekdays and weekends, from multiple network locations and computers and always got the same error when clicking to manage the benefits. From the details below, I believe this is programmer speak for "this is a bug in the system that we just fixed and it was only affecting less than 10% of customers and we just released a patch to resolve the issue". Spelling errors below are reproduced exactly from the email.

Thankfully, the new CDW issued agreement numbers did let me in to benefits management and I was subsequently able to get in and allocate myself as the MSDN downloads member.
