oscommerce modifications

Modification #1 Need to add a form on the [login to view URL] page where the user is asked to enter their RedHat network login into a text field – information saved to the database and available in the Admin > Customers section and also sent to the clients & customers email. The field in Admin > Customers needs to be updatable. Modification #2 If a user adds a product(s) from a certain product section sectionthen underneath those product(s) on the [login to view URL] page we need to ask if this is a new license or a renewal (using radio buttons) – if it's a renewal then a drop down list of: day (1-31) month (1-12) year (1995 – 2099) is displayed. (An exampe: [login to view URL] | I can do this form stuff if necessary) This information should be saved to the database and be available in the admin panel under CUSTOMERS > ORDERS along with the exact product and also sent by email to the client & customer when they receive the email informing of a successful product purchase. Full brief attached.
