CSS and IE issues

My website is 99%. I just need sort out some CSS and IE issues. They are as folllows: QUICK CSS FIXES - Change the size of the columns on the contact page; - Apply conditional fixed positioning to the forms on the product pages (the ones where customers personalize their cards) [login to view URL] - Make the "Home" link on the homepage work; - Adjust the spacing of the lines when hovering over the thumbnails (product pages); - Delete "Cartões Mais Recentes" on the home, leaving 30px between the two white rectangles; - Leave 30px under the product sorting options on the product categories pages - Duplicate the 3 colums of the footer (i'll add other links there). INTERNET EXPLORER FIXES - Product thumbnails are not showing on the product pages; - Radio buttons and checkboxes look weird. Can we make them look like in Chrome? - Positioning of "Adicionar ao Carrinho" (Add to cart) is different from the one in Chrome; - In the forms, the button reads"Browse" instead of "Escolher arquivo" (in portuguese); - Product price is not showing in the forms. OTHERS - Integrate Facebook comments in all pages; - Clean all the unnecessary code and javascript, so that the page load time decreases to 2 seconds or less. Here is the link for my website: [login to view URL]
