Thanks again for the initial proper wording for what I was looking for. I couldn't have gotten started on this project without it. In case you're interested, here's an album of the project.

It's still not as neat and tidy as I'd like, but it's FAR better than it was before I had room to work with. The next step (when I have the funds) is to replace the switch with a POE model for the two IP cameras (I currently have one with an injector), and I'd like to get a backup battery in that lower left corner. Overall I'm quite pleased with it, and the wifi reaches very far through the cabinet (though I have another AP on the top floor anyway).

Thanks again!
