how did they do this in the navbar then link it to a new page?

[shinng]

here's the link to what i'd like to implement:
http://www.thevbgeek.com/index.php

what i want to do:

• add similar "Navigation: Purchase Download Wiki" on the navbar that is colored to make it stand out -----I will also include a link in the custom drop down menu, but i also want to add it to the navbar.
• when clicking on "purchase licenses/renewals" in the drop down navbar, i'd like to put something similar as a drop down menu
• once you click "purchase licenses/renewals", how do you create a landing page like they did and include an "add to cart" at the bottom of the page?

basically the point of wanting to do this is that i will have a "vip member" service as a subscription. as i currently understand vbulletin, there is no way of giving an option when registering like invision board has at the time of registration. (unless there is, please let me know!). so the only way i know how to get this to work is for the members to either

1. register then choose to become a "vip member" or not
2. they can click on the link on the navbar and directly become a "vip member"

i know it's a lot to ask, but i'd appreciate anyone's help in the bulleting list above and the scenario below it.

thanks.
