Wordpress updates(repost)

I have updates to be made to a Wordpress site. 1) there is a form that requires modifications. It is on the bottom of most pages. I need to add a field "Product or service you are interested in" 2) Where do I set the email that form goes to? 3) Make the new shopping cart look like the old - in the old, the pictures are all the same size and there is an 'Add to cart" button You can see the old site at <[login to view URL]> and the new site at <[login to view URL]>
