Basic level question - Wordpress as CMS with blog attached

We're in the process of re-building a company website using Wordpress and ATA that we're very excited about. This is my first experience working with Wordpress, and I have a basic usage question.

We're currently putting the site together with a series of 'pages', but we would also like to have a blog for the company. I'm probably missing the obvious here, but how do we implement all the blog functionality of WP while the majority of WP is being used in a non-blog manner?

The test site that I'm working with right now is here - http://duartefruittrees.com. The gist of the question is how do I set up a 'page' with a blog, or am I going in the wrong direction with this?


Thanks for your time
