Follow that product removal up with a
Code:
zen_redirect(zen_href_link(FILENAME_CHECKOUT_ONE));
... after having set a message to the customer via the $messageStack class (which probably will require a global $messageStack; statement) to let them know what's going on.

On the page's re-display, the shipping and taxes will recalculate based on the updated products in the order.
