One make sure in godaddy that you have set the name servers to
ns1.t35.net ,
ns2.t35.net (this may take up to 48 hours max to switch)you'll add the domain in your cPanel
(sounded like you have done this)The files that will go in this account, should be placed in a folder under your main account
**new domain with FTP**
If FTP isn’t made when the domain is set up just simply make a new ftp account pointing to the folder of the domain.
(all new domains will use the main accounts address, example: account@1stdomain.com)I hope this is clear and I hope this gets you going

(PS I am working on some Flash Tutorials for T35 so you'll be taken step by step)
