Exchange 2010 CAS Array after deployment

I had to do an emergency deployment of Exchange 2010 because my other Exchange 2010 box was failing quickly and I learned the hard way that I should have had a CAS Array in place even though I only had a single Exchange server. After moving all the mailboxes and taking down the failing server none of the Outlook 07 clients would connect so I added a host record on the internal DNS with the old server name to point at the new server IP and then had everyone run the Repair option in Outlook to get connected to the new server.

I have done some testing by adding a new mail DB, added one mailbox to the new DB, then added a CAS Array (cas.domain.com) to the server, and then changed the RPC server on the new DB to point at the CAS Array, ran the Repair option in Outlook, and everything worked as it should. Also adding a mailbox after the CAS Array was in place worked as it should.

My question is besides running  the Set-MailboxDatabase –RPCClientAccessServer command to apply the CAS Array to the production mail DBs and having everyone run the Repair option in Outlook again to point at the CAS Array is there anything else that I need or should change in my Exchange config?

Mainly I am concerned if I should change the internal addresses on OWA, ECP, ActiveSync, OAB, AutoDiscover, or EWS?
These are the current settings:
OWA, ECP, ActiveSync, EWS:
Internal: servername.domain.com
External: mail.domain.com
OAB, AutoDiscover:
Internal: servername.domain.com

Thanks for reading my novel, just wanted to cover everything I could think of.

I agree with you both but I went ahead and changed everything internally so that I wont have any issues down the road whether it is an emergency or if I decide to expand beyond my single server. Thank you both!
