Changes to Magento theme

We have a sunglasses website that has been created in Magento using the GreyScale template ([login to view URL]). We need a number of alterations made to the theme. The installation runs 5 websites so please be careful to only make changes to affect this one website. 1. Product page - see attached mockup a) Product image fits width of main pane and remove zoom functionality b) "More views" and Add to cart are moved. c) Product Name is moved to fit full width of pane and font size reduced to 25px in CSS just for product title in this page. d) Add Facebook like icon in position shown - [login to view URL] e) Add to Cart button change to light yellow background (#FFFF99) rather than grey 2. Checkout Page a) The Product Name needs to appear in the Product Name column of the checkout (currently showing price?!) b) Remove Estimate Shipping and Tax section of Checkout 3. Front Page a) Add a full width banner scroller to top of homepage below the virtical menu. The theme demo shows a scroller so this may be present somewhere already or install: http://www.magentocommerce.com/magento-connect/Theodore+Doan/extension/4330/my_ibanner#overview b) Add layered navigation to the left column 4. Product Category Pages a) Add a 1px grey border around the category images e.g. Alexander McQueen skull image via CSS b) Increase default products per page to 15 5. Top Menu a) Turn the top vertical menu into a menu linking to CMS rather than categories (add some dummy pages) About Us, FAQs etc. Let me know how I can add to this.
