355547 Magento product design change

Hello, I configured a Magento shop with small changes added to standard version. Most products are bundles. Requirements are related to 2 pages, as follows. There are 2 categories of products with specific design: Category 1 - contains 3 bundles that only differ by price of bundle item options. When enter category page, the product details can be seen (like product page-can be used)-see attachement; as bundle options are the same for all products, the first product options will be shown by default, but un-editable until product is selected from list. Category 2 - contains around 10 bundle items; one of the bundle options is size; category page will show standard - product thumbnails; requirement is to have Rollover functionality that will show size option with its radio selections, quantity, and add to cart button (all in Rollover); product will be added to cart with the chosen size option and the options not shown as default set up. Change of product in Category 1 and Add to card in both (and all other standard pages) will be done without page refresh (Ajax).
