Adjust web page as requested, fairly simple

Please see following link. I would like this page to be made to look more professional in particular 1. The main Tshirt image, I would like that to be a mouse over using CSS. NOt sure if it can be done but then I would like the smaller images to be able to be clicked on so that they change the larger image as well? 2. Insert a zoom box or similar to the Size Chart wording, I have a document I have made to use as the image. Please see this link for what I am after, click on the words size chart [login to view URL] 3. Change the Add to cart image for paypal to something more modern that ties in with the colour scheme of the page. 4. Background in table to be changed to match background colour behind it. The table probably needs fixing up? 5. Incorporate Gehyra Dubia swing tag information on page somewhere so that it fits in better, looks more professional. The colours can be changed on it if needed 6. Insert a custom View cart button for paypal in right hand corner under banner, I would like a picture of a cart that is a bit funky? 7. Fix up spacing so that detail is more condenced and looks more professional eg. [login to view URL] 8. Tweek the page so that it is more efficient, the main part centred and easy for me to manage, I also want it to be a fixed width to suit most browser sizes and to work in most browsers. I would then like to use this page as my template for my Tshirts. I am keen to get this done by Friday.
