Create Magento Module to extend Grid/Matrix ordering system

I have a currently multi-store site set up. One store for retail and one for wholesale. In the wholesale site, we have Matrix ordering. This has been implemented using the Magento mechanics module (see [login to view URL]) This takes place on all product pages (via installed module) which takes all associated configurable products located under the configurable products and displays a size and colour grid. I need this extended so the products matrix appears on the Shopping Cart Page with (proper formatting) On the customer email confirmation, and in the admin (this can be done with a simple print PDF fucnction) NB: This has to function only for wholesale website, the retail website must retain all existing functionality and must be thoroughly tested.
