I want to remove all the printer Presets and go back to the original printer settings that were installed with 10.6.3, including resetting the Standard preset. Which printer pref files are safe to remove and which ones store the information I want to delete?
The files to remove are in your home directory's Library/Preferences folder, and they are in the following format:
com.apple.print.custompresets.plist
com.apple.print.custompresets.forprinter.<printer name>.plist
The Standard preset being changed is probably a result of saving a setting as the default, so you can remove com.apple.print.PrintingPrefs.plist also.
If you want to make everything revert to the original settings and don't mind re-addin your printers, you can remove all the files starting with com.apple.print.
Hope this helps.
