Transferring Existing Domain

How do I get to the page to change the name servers for my domain name?
This page is called the "Domain Control Panel". Click the gold menu item "Domain Names", bellow in the blue menu, click the menu item called "My Domains". This will bring up a list of all your domain names. Click the domain name you want to edit, and there you are.

The nameservers are:

NS1.HOSTMONSTER.COM
NS2.HOSTMONSTER.COM
