Google Analytics Help + Setup

We are an ecommerce site looking for help setting up our Google Analytics properly. The website is currently running on joomla and using Virtuemart for our shopping cart. The problem is that we have multiple promotional landing pages and we are having trouble tracking each page specifically. We need someone to create specific analytic pages for each individual landing page so we will be able to track them and determine where these customers are coming from (there needs to be specific data for each landing page). We also have "adwords" already in place and need to be sure that they work well with the analytics. Essentially we want to be able to track the exact location where most of our leads are coming from. From entry point to lead generation. Make sense? If so, then we can work. If you have any questions please contact us.
