@akingston47: What you’re looking for is basic WP functionality. If you want to see all of the posts for a category, navigate to the category index page/URL like @Jamesmarsland suggested.

If you want to do this on a page, you need to modify WP “the-loop”. There’s a whack of information on the WP codex about how to do this sort of stuff.
