Custom Magento Changes (3)

-On our packing slips generated from our Magento cart, theres a line under the shipping method that displays shipping charges (ex: "Total Shipping Charges $14.48). We would like this line removed. -We have had a custom project done to the cart that enables us to change attribute set names after the product has been created. It worked fine, until now - but now more often than not is does not work and re-directs back to login page. We would like this fixed. I have an example I can give you. -Please configure the "Stock Availability" field on the "Inventory" tab to automatically re-set to "In-Stock" when the quantity is greater than 0. Right now the system automatically changes this field to "Out of Stock" when the quantity gets to 0, but does not go back to "In Stock" when the quantity goes above 0. This has caused some problems with items not showing up on the front end after they have been received, because this field has to be manually changed back. -On the "Contact Us" page, can you update the title of one of the fields from "comment" to read "Comments or Questions, please reference your order number." -Delete 'search terms' and 'RSS' link in the footer, and anywhere else they appear as links on the site. -There are some extra bullets, and links missing bullets in the footer. Can we have this fixed? -In Home > Customer Service, can we remove 7 of the links that are not needed? I will specify later which ones they are in the PMB.
