Special Category

I am trying to make a product catelogue and was trying to make a special category for items marked as a deal. This category will be selected along with another category – ie if i am selling a monitor at a discount price i will want it to be in the monitor category and the special category.
The problem i have is i want to display the special category at the top of the page with its own style and only display two of them. In addition I want the two items that are displayed as special to be hidden from the main posts. As well I need to be able to display this category as a normal category so people can see all the deals in one category.

Hope that makes sense any help would be great.
