Richard Byrne has really done a good job of compiling resources. I particularly like his work to put together a guide to the Google tools available to teachers. With so many schools running Google Apps, this is a great resource for educators around the world.
I encourage you to peruse this blog. Tons of helpful resources are there. For example, Freeology offers printable resources like graphic orgnizers for teachers (see Byrne's blog post for more details). You can find virtual field trip resources and even links to tutorials like Mac for Beginners.
Make sure you are taking some time to explore the many tools available on the web to help students learn and make this type of professional reading part of your regular diet.
