I think there might be others in registry (i.e. Environment Variables). E.g.:
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R19.1\ACAD-D001:409\Profiles\<<Unnamed Profile>>\Dialogs\AcPublishDlg\DefaultDwfFormat
Note this is under the profile, so you might just want to export/import a profile to have it match across different PC's / users.
Another thing is ETransmit Setups. Those are saved under sub-folders of:
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R19.1\ACAD-D001:409\ETransmit\setups
Note these registry paths are for 2014 Vanilla, might be slightly different for other versions / verticals.
