You can technically start within any domain but I prefer to start in the root domain then work my way down to the child domains. You need to run adprep32 or adprep to prep your domain and forest for a Windows 2008 Server R2 to be added as we DC.

There is a root domain and two sub domains. I'll carefully read the documents you posted and try in an experimental environment first. Thanks for your suggestions.
