First make sure before you do go under your mainenance screen and deactivate your PSN account from that playstation.
From there you can either do a full HDD Reformat
Delete all your games one by one, Delete any video or music you have stored, then delete all your users by selecting Triangle when highlighting the user name when you are logged in as that user. If you have only one User you will need to create another user, then log back in under your original user and delete it following the step above.
Deleteing the user should delete all game saves, messages and trophy information.
