I'm trying to assess the usage of a particular collection and am wondering if the 'issues' field in the items table represents all issues: Ie., both from the old_issues and issues tables.

Yes -- items.issues gets incremented every time an item is checked out, so if all you need is a count, you don't need to include either the issues or old_issues tables in your query.
