If you want to edit an existing category's information, you can click the "edit" button at the end of the description text in the category. That will take you where the information is currently stored. Most of it is in modules, but some topical categories still have their info in templates, I'm currently working on moving them over but there is a lot of reorganising to be done too (to make the tree structure a bit more sane).

Creating new category names is a bit harder, but my general suggestion would be to go to the new category's desired parent, click its edit link, and then add the new category name to the module it sends you to.
