You can also hit 'Export' on the Cam dialog box to save your Gerber settings in a text file. You can use 'Import' to bring this into other designs or it comes in handy if you want another way to tweak things besides the GUI.
I also use an individual folder for each design's CAM. If I was only working on one design at a time then PADS has some nice features if you keep everything in the common folder. Unfortunately I'm often working on multiple designs so I can't have them co-mingling.
