Shipping charges, method and form variables

I'm creating my own shipping charges via javascript (well, and other stuff) on my client's order page (we're using a 3rd party fulfillment company), and I'd like to have the shipping included in the cart before the final checkout so the PayPal transaction reflects my shipping charges. So, I'd like to be able to have the shipping charge and the shipping method (i.e. UPS Ground, FedEx 2nd Day Air, etc.) as form variables which PayPal expects. How can this be done (and what variable names are used for these?) Also, I'd like to silence the warning about the "no Shipping Rate available" message on the final checkout page, or even better, for the backend to recognize my initial variables and print them nicely. I don't see a template for this page. Thanks in advance.
