It's pretty vanilla on the back end, Walt. I run a small e-commerce site on Drupal Commerce where we do on-site processing, and slowly the tweaks I put on my site work their way into core. (Incidentally it's also the site I originally developed the Commerce Flat Rate for.) We're limited to what you can do with Views for the most part, though the roadmap for Kickstart 2.x involves bringing more customizations to bear there.

Spicing the Views up with bulk operations seems to be a pretty common task, and I think we're all still waiting for an "Entity Comment" module to appear that lets you attach comments to any type of entity. Aside from that, you may find a few other administration enhancement modules in the contrib list at http://www.drupalcommerce.org/contrib.
