Added Upgrades Packages - Now What

I have created an Upgrade package for Ad Removal, and users can either sign up for 1 month, 3. months, or 12 months of credit. How do I now assign the removal of ads to that particular user?

Do I need to coordinate it with the "Sitewide privacy options for WordPress MU" or "Who Sees Ads for WPMU" plugins?

Or do I give the divs in which I place my ads a property that is either shown or hidden?

Thanks in advance
