Well, I figured out my issue and I feel like a tool; I often stick an asterisk in front of folders so that they appear at the top of a new column (I'm a Mac guy)... My folder with all my IR's had just such an asterisk, and neither Kazrog or NadIR could navigate it. It was showing but not loading if that makes sense. Went back and removed any potentially difficult to navigate symbols (*, /, :) and everything is loading just dandy now.
In terms of navigation the Recabinet is awesome, and yup, it stores named presets how ever you want 'em. I plunked down my hard-earned $ as soon as I got it working.
Now to the Kazrog sandwich!
