You must have both the internal and the external name in the registry entries, otherwise it doesn't work. Trying to condense the registry entries will not work, and I don't see much point in it. Do remember to make the change on the domain controllers and ensure that you are pointing the registry entries at Windows 2003 DC/GC. The feature will not work with Windows 2000 DCs.
If you add additional Exchange servers, but not frontend servers, then the same registry changes need to be made. If you are also putting domain controllers in to those sites then make the changes to use that, rather than coming back to domain controllers on the "home" network.

Same thing, but change the names to local DCs and Exchange servers, or something else?
