It sounds like Category-Based Fee/Discount may work for you. You can set up discounts based on the number of items purchased from a category or categories.

However, it doesn't have a setting to require *all* products within a certain category. If you wanted to do that, you could use Product-Based Fee/Discount with the "ALL" comparison type, but you'd need to list every product in the category (including adding new ones to the extension when you create them).

Feel free to take a look at the screenshots and demo site (which includes some examples of various set-ups using the "Show Examples" button), and if you're interested let me know at www.getclearthinking.com/contact if you have any further questions.
