I don't know that software so I'm not sure what you'd do or not do. However, if it's used to restore preferences, there are ways to save them that don't require software.
Trashing your preferences is a catch-all fix for a lot of wonky FCP behavior. Once they've been trashed, FCP remakes them from scratch as soon as you open FCP again. That means that you'll have to set up all the settings and scratch disks to the way you want it. Once that's completed, you can copy those preferences and save them in another location in case you ever have to trash your preferences again. If that happens, you'll only have to copy back your saved prefs in order to have everything as it once was.
Talking about the GRaid: are you giving the drives to another editor for editing, or are they editing on your computer? If they are working on your computer, then there is no reason to have your project file be on the same drive as your media.
On my system. I have the project files on my system drive. The media is on a media drive. And the autosave vault is on a 2nd internal drive. In the scratch disk settings in FCP you can set the desitnation of your autosave vault. It helps to keep it's location on a different drive than your project files. If the unthinkable happens and you have a catastrophic meltdown on the drive that houses your project file, you'll still be able to access your last autosave file and continue working.
