Wordpress E-Commerce Tweaking

I have a wordpress installation that I have added the wp-ecommerce plugin with the "gold cart" upgrade. I need the following customization items completed. 1. [on checkout page] We need to change the title "Shipping details" to "ticket holder info" 2. [on checkout page] We also need to remove all entry fields under the "Shipping details" section and leave only First & Last name (and these two fields need to be REQUIRED and should display an asterisk) 3. [In wp - ecommerce admin section - on the product tab/page] When creating a new product using the existing e-commerce admin section I need to install a field where I can add a variable dollar amount FEE to each new product. EXAMPLE:I am selling a concert ticket for $10...when the customer proceeds to check out there will be a separate line item fee that says something like: "Service Fee - $2.00" > When the customer submits the order the fee should be added to the total amount and sent off to [login to view URL] for payment processing. 4. [wp - ecommerce sales page] The cart will already export a csv report of total sales. We need to add 2 more types of exportable csv reports. > a. Because this cart is being used to sell concert tickets we need to be able to generate a "will call list" by creating a csv export that will show the first & last name of each purchaser for a particular product/ concert. > b. For every product there currently exists a "qty available" or "stock keeping unit" amount field for every product. We need to create a csv report that will tell how much qnty remains for each product.
