for extra security, what i would suggest is zeroing out the hard drive. when you delete things off a hard drive, it doesnt actually remove the data, it just marks that part of the drive as reusable. if you boot up from the restore disc and then open up disk utility, select your hard drive, then the erase tab. you should see security options in there somewhere and an option to zero out the drive. what this does is just write over the whole thing with zeroes so your data cant be retrieved.

I would do as joe says, there are some options when reinstalling. Do the Erase and Install and you can even have the Installer do up to a 35 pass wipe of the hard drive, insuring that the old data is gone leaving a fresh virgin copy of OS X after it's done with all the standard applications.
This is precisely what I'd do. That way no one can get at your personal data on down the road. As I recall the DOD standards call for a seven-pass wipe of government drives -- FYI.
