For mass-categorization, you might want to use MassCategorization script on Dev Wiki.

For mass-editing in general you can use AWB or Pywikipediabot. It is also advised to request a bot flag from Staff on an account you want to edit these pages from (that should be any your account other than the one you use to communicate with the community) so you don't flood RecentChanges with your edits.
