Netbilling Merchant Account Integration Into Cakephp Site

I have a merchant account setup through netbilling. I need this integrated with my existing site which is made with cakePHP.

Further, I need integration with twitter and facebook connect.

I also have a chat support script that I need integrated.

The fourth thing I need is a tracking table in mysql. Every click into the site should be captured and cookied. The table should have columns: datetime, subid, referrerUrl, currentURL, previousVisitID, memberID, isExistingMember. The memberID should be saved here if/when the person signs up through the site.

Please msg with your previous experience. I need a clean integration. Knowing jquery or something similar is a huge plus
