Okay, I followed Podz's tutorial on moving a wp site from one domain to another. http://www.tamba2.org.uk/wordpress/move/
I also followed the database restoration tutorial: http://www.tamba2.org.uk/wordpress/restore/
Two separate domains, two separate databases.
Everything went fine, except for when you try to go to a page in the new site, such as http://www.hagamanfire.com/fire-trucks-apparatus/ I'm getting an "Oops! Page not found" message.
I did check in the wp_options table that everything be set properly, and I tried going to that page from the link in the sidebar "Fire Trucks & Apparatus" (however, regardless of the page you try going to from that list, this is what happens.)
