Where can I get great instructions on how to use iWork. Especially pages?

Howdy. Have you checked the tutorial and/or the user guide?
Otherwise its a very simple app and you’ll learn a lot by just trying things out, ie try different templates and menu options.

If you have a .mac account, go to mac.com, click on learning center. Choose your apple program you wish for help with.

If you don’t have a .mac account, you can use sign up and get a 60 day trial.

You can probably get started with the basic video tutorials for document creation and management (http://www.apple.com/iwork/tutorials/#pages-create-0) and then move through the tutorials and down the list. Once you start getting a little more creative, the layout tutorials will prove useful (http://www.apple.com/iwork/tutorials/#pages-layout-9). Good luck, and have fun.

the tutorials apple makes are really good. Their are walk thrus and quick tips. They really to help.
