Hi Doug, You need email and password when you are using ClientLogin as the authentication mechanism (which is also the default). If you are using OAuth, you don't need to set them, but you have to set user->SetOAuthInfo() instead. See http://code.google.com/p/google-api-adwords-php/source/browse/apps/sample-webapp/public/login.php for details on how AdWordsUser is initialized in this case.
You need one of ClientId / ClientEmail when the logged in OAuth user or the Email is an MCC account. This is used to identify the AdWords account against which the calls are happening. Hope this helps. Let me know if you have more questions. Cheers, Anash P.
