Magento extended navigation menu

Hello, we would like to implement an extended navigation in our website. Please view the attachment. It has to be exactly like it’s photoshopped. What we want: - A navigation dropdown width of the entire navigation - On the left side (50% of the navigation) space for 6 x navigation level 1 and level 2 - On the right side (25% of the navigation) a block in which we can upload a image in the backend of magento (for example sale). - On the right side (25% of the navigation) a block with 3 products in the spotlight. We have to be able to enable this by attribute such as – Attribute: Is displaid in upper navigation: category x. We have to be able to fill out the category number manually. This attribute must be visible and adaptable in the product backend. It has to be implemented on [login to view URL] (it will automatically be visible on all the other frontends). Can someone make this?
