In includes/english/YOUR_TEMPLATE/page_2.php (or _3 or _4), change the fields I've highlighted in red:

Code:
define('NAVBAR_TITLE', 'Page 2');
define('HEADING_TITLE', 'Page 2'');

define('TEXT_INFORMATION', 'Page 2 information goes here.'');
In answer to your second question, you can do that with EZ-pages. Check the Holzheimer site in my sig and look in the "Important Links" box. There's a link to other sites used by the site owner.
