The government has a new site called DigitalLiteracy.com which serves as a collection spot for links to resources and tutorials to learn computer and Internet skills, put them to use in finding jobs, and help children stay safe online.
Under "Learn the Basics" is a section called "Child Online Protection" which includes help with combating cyberbullying.
