How do I change a SBS 2003 IP addresses

We are running Windows Server 2003 for Small Business Server. The server is configured as a DC and has a single AD and DNS and DHCP server. Exchange server 2003 is also installed on it.
We are changing our partial T1 to a full T1. We are also combining data and voice together. For that reason, our ISP has given us a new range of IP.
My question is how (and where) do I carefully change my external server IPs without affecting the work performance of the company?

Unless you are using external IP addresses internally (which is doubtful) and do not have a firewall between SBS and the internet (possible, but not something I advise) there is nothing to change on the server.
The only things you have to change are the IP address of the host name used for your MX records.

However as you haven't provided enough information I cannot tell you whether that is all that you need to do.

I do have a firewall (firebox edge) between the T1 box and the server.
Also how do you change the IP address of the host name used for your MX records?
Thanks For your help!

I forgot to mention that SQL server is installed on the server.
And what about the settings on the DNS server, do I have to change anything on it?
Thanks,
