Google Apps TrainingSynergyse is a Chrome extension that provides training in the task you are interested in, when you're interested in learning it. It looked pretty slick during the demo, but when I checked out the site, I saw that the free version limited you to 5 lessons. After that, it was $10/year.
Ask the Gooru is a second Chrome extension that live in Gmail and provides access to training videos right on the Gmail desktop. These quick and clear videos are also available on their site for Google Apps users who don't have Gmail access.
The folks at EdTechTeam who put the Summit together also have a great set of tip sheets on their website.
