Ok, if I understand you right, you have two problems:
1. The navigation is pulling in pages from Dynamic Drive, not the pages you want to link to.
2. It's loading them into the navigation frame, not the main one.
Have a look at the source of this page:
See you've got stuff like:
<li><a href="http://www.dynamicdrive.com/style/csslibrary/category/C1/">Mission Statement</a></li>
That's where you put your links. And to get the link to open in the correct frame (on your site, the main frame is called "right"), you set its target
So, for example, if you had a page called "mission_statement.html" that you wanted to load from that navigation link, you'd change the code above to read:
<li><a href="mission_statement.html" target="right">Mission Statement</a></li>
