After looking around some more I realized the answer to part of my question was pretty obvious, so I figured I’d post it here in response to myself just in case someone else searches the forums with a similar question.
To transfer Render Settings and Output Modules it is as simple as going to Edit>Templates>Render Settings…/Output Module… and choosing “Save All…” to save a file with all your settings that can then be loaded, using the “Load…” button in the same place, on another machine.
Still haven’t found a way to transfer “Preferences,” but those are probably best set up on a machine-specific basis anyway.
