How do you pull call center reports when you’re using a call-blast support queue?

Hi IanBrig, welcome to the community.

This support article explains each of the detailed report parameters: Detail Report overview, Unfortunately, it does not capture everything you are looking for at this time. 

Counting the number of In, in the Direction column will tell you How many inbound support calls actually hit the queue?

Direction - In + Type - Hangup should indicate a call that was not answered. If you look at these and the Extension listed as well you should be able to identify which agent/extension is not answering calls.
