Ok, the easiest way to go about doing this, is to register the new domain (you can either do it through lunarpages, or through a 3rd party like
www.the other hosting company.com). when it is purchased, set the DNS nameservers to the lunarpages one (see the FAQ pages), and add the new domain name in your CPanel, using the bottom near the bottom of the list: Parked domains
You should then be able to use both domains to access your site, and be able to setup email on both domains. You can setup the email on the old domain to auto forward to the new addresses as well.
You can see what I mean by this setup:
www.jokeawhenever.com <- my main site
www.switchfootdesign.com <- my parked domain (until I get the site up).
Both point to the same server/files but have a different name, and email addresses
Post again, if you have any problems!
Good luck!
