Help with AWStats in Plesk

I have some basic questions about how to configure awstats that's been installed in a plesk environment on a Linux server. For instance: 1. Where are the domain configuration files stored? 2. How do I generate stats from past web logs? 3. In another environment, I had the option of "updating stats now" as a link on the AWStats page. How do I add that to the existing pages generated? I'm thinking if you're experienced with this, we could connect on IM for an hour and straighten out a lot of issues. Let me know if you're available to do this. Thanks!
