Gift Wrap (Magento 1.7) - repost

Hello, We would like to have a custom gift wrap option in the checkout page of our Magento 1.7 webshop. (1) At every product line there is a possibility to choose for gift wrap by clicking the select box. When the user clicks on this field, the amount of the gift wrap will be added with the price (after the user has choice the wrap , should be ajax ). An extra line at the price list overview will appear at (3): This amount will be taken to the final checkout (onepage ) including the description. (2) When the user selects gift wrap, then this part will appear. Not before. So when the user enters the page for the first time, this part is not shown. This should be AJAX based. The page should not be reloaded. The user can select couple types of gift wrap. At the top is the name of the wrap, under that an image of 100x100 pixels and under that a select box. When the user clicks on the image of the paper a light box will appear with an image of 600x600 pixels. The user can close this lightbox by clicking in the lightbox on the X-symbol or by clicking outside the lightbox. (3) Here will be shown an extra line: This line will only appear when the user has selected gift wrap and will be removed when the user has deselect the field. (8) When the user selects gift wrap, then this part will appear. Not before. So when the user enters the page for the first time, this part is not shown. This should be AJAX based. The page should not be reloaded. Backend (4) In the line of the product order will be an extra text under the SKU of the product. If a name is filled in on the checkout page this will be also shown here. If no name is filled in, this field will not be shown. (5) Also at the price total will be an extra line This will also be shown at the invoice, which the system generates. E-mail (6) On the order confirmation and the invoice there should be an extra line where the choice of a specific item with gift wrap is written. If no gift wrap is selected this will be left empty. If the user has given a name on the checkout page this will also be shown here. If no name is given, nothing will be shown here. Both should be on the confirmation mail of the order when the order is made and on the invoice e-mail after the order has been sent (manually in the backend). (7) Also the amount of Gift wrap should be in the total price overview in the conformation and invoice e-mail.
