Magento -- pull in 3 products on 1 page with nav bar, back-end admin

Our magento store needs to have an additional feature built for front-end and back-end. Our products are a bit different. One product, will have 3 separate Phases. Phase 1: - Simple product - Have its own set of images - Have its own comments specific to Phase 1 - Have its own right content block and its own 2 review buttons Phase 2: - Configurable product - Have its own set of images - Have a comments section specific to Phase 2 - Have it's own right content block and it's own add to cart button and 2 review buttons Phase 3 - Configurable product - Have it's own set of images - Have a comments section specific to Phase 3 - Have it's own right content block and it's own add to cart button Backend via Magento Admin: - Need to be able to somehow link 3 separate products together -- 1 simple and 2 configurable under one product and one URL. - Backend needs to be user-friendly Front-end: - Need to have just 1 product page that has a navigation bar at top with 3 Phases -- PHASE 1, PHASE 2, PHASE 3. - When Phase 1 is active, the images, comments, buttons, for Phase 1 are shown. When Phase 2 is active, the images, comments, buttons, etc. for Phase 2 are shown. Same for Phase 3 - Basically need to be able to create one page that will allow me to pull different images, comments, buttons and layout from 3 separate products. The Phase buttons at the top (PHASE 1, PHASE 2, PHASE 3) should have background images that I will create. The Phase that is active will have a different background image to show it is active. The Phase that the product is currently on will also have a different image. For example, if a product is in Phase 3, the Phase 3 button will look different than the others, even if it is not active. So buttons will have the following states: for each phase (meaning 3x each) - current phase button active - current phase button inactive - non-current phase button active - non-current phase button inactive The links of the Phases (PHASE 1, PHASE 2, PHASE 3) can be clicked to open. IMPORTANT: When the page first opens, the highest active phase will be showing -- if the product is in Phase 3, then the Phase 3 content will display, with the Phase 3 images and comments is shown.
