There is a lot of info on the AdWords site [adwords.google.com] that provides a great primer. Review of the threads in this forum will help and if you have specific questions about how the program works (but not specifics of your site) post em' here and you'll find people willing to share some insight.
Having attended 2 of the sessions in London, I must say they were very very informative.
I would even be willing to stand and share some tricks, and I am sure others would do the same.
come on Mr. Kordestani and co, get it sorted please!
