Magento CSS modification

We need some modifications on 2 magento stores (URL will be sent by MP) : see images attached *1st store : we installed a custom menu extension( see : [login to view URL]). the menu works well with default skin but not with our skin (it is impossible to navigate in sub-categories). The problems comes from css file (we tested it with default css, it works) 2nd store : * Modify product page : Image should be resized and placed on the right (we will send you an example of what we want exactly) Add complementary products in the bottom of the product page delete small description (at the bottom) delete complementary information (at the bottom) * Listing product pages : On all categories with displaying of products only, image of the product should be resized (square) Title "Acheter" should be aligned woith "add to cart button" below * Featured product "nouveau produits" Correct display of product image + Title * Advanced search / recently consulted products ( Right column modules) - Advanced search should be below search module recently consulted products (produits récemment consultés) is larger than other modules * Cheking : paypal modification : replace Paypal logo by CB logo (see file attached) and replace "qu'est-ce-ceque Paypal"by Carte Bleue On vertical menu : add logout link wih same font and color
