Oscommerce Checkout Work

I have an oscommerce store that currently operates using Google Checkout but I am currently setting up merchant facilities to take bookings on our site. It is going to take some time to set up the account so I would just like to get the process setup on our side, much of which I have already done using Dynamo Effects one page checkout which works well but I have some small issues I need to resolve which can be seen in the attached document, but to highlight: (1) Replicate Shopping Cart Products and Pricing view in [login to view URL] to [login to view URL], therefore including price, people, tour date and pick up info. (2) Add in Security Card Number (3) Add in Credit Card Type (4) Remove tour info from Step 4 of [login to view URL] Obviously, all data needs to transfer to Admin succesfully and also to the email generated to the client. Additional info can be found in the attached. Thanks.
