It's just not an option to rename a category -- the feature doesn't show up for anybody. It's a necessary evil of all wikis :) Once a page is in the "category" namespace, the page title is stuck as it is. You can redirect a category page to another page, but that sort of defeats the purpose of a category altogether, so recreating it is the only option.

Removing stories from a category should be as easy as going the story's page, editing it, and deleting the category you want to get rid of in the same area where you added it before! :) Sometimes it takes a minute for both the story page and the category page to update themselves, but it'll still work fine.
