Need help with categories to show featured items by default

I am working on a site which will have several categories with products under each category. (essentially a store)

Using some of the tutorials for category menus, I managed to get it working so that when you click a category, it displays a list of the products for that category. Within the products section, there is a checkbox which determines if a product is featured or not.

Currently when I go to the page ALL of the products are displayed by default. I don't want to display ALL products by default (unless the All Products) link is clicked. What I need is for the default display to show only the products with the featured box checked, so that when a visitor first enters the site they see the featured items.

Any suggestions on how that might be achieved? I have posted the code from the page below and the link is: http://ncblades.com/test/

Any assistance will be appreciated.

Thanks,
Kevin
