Dan Petrovic put together one of the more useful Google Hangouts I've yet to see by a non-Googler.
He had several SEOs on the Hangout where he went through a long list of SEO related questions and asked them to answer them in order. The hangout is about 1.5 hours and they go through basic and more advanced questions.
If you have the time, you can watch it or just let it sit in the background as you listen to it.
