NEED HELP ASAP! Magento Template Help

We have a Magento Store and we're just needing some basic help of getting the category / navigation working correctly. test dev site: [login to view URL] ex: when clicking "Beer Brewing" top navigation, it then needs to show secondary nav categories as images, then once those are clicked, either go one nav level deeper, or show all products. (image attached of example page of what should be shown once a main category should be clicked, and need it easy to be able to swap out images) Right now the navigation goes directly to products. We have all the products put in, and setup correctly into the right category, we just need help putting that together on the public facing site. Also right now all the products stop after 9 products with no pagination, so we need to add pagination to the bottom of the products pages.
