DSL's static IP address. His address is like 64.X.X.89 and they have it as 207.X.X.X instead
I would imagine that the '207' IP is where they have it 'parked'. Upon review of the site, I found that they (appear to) have web-based account management (as I suspected, I have this with Register.com). You should be able to modify his DNS records from there... Have you checked out the web-based management?
As to mail servers...
