Answer 1

I don't have access to a Google+ domain account so cant help you test this. However I have a generated sample that might get you started

Oauth2

  /// <summary>
        /// Authenticate to Google Using Oauth2

        /// <param name="userName">The user to authorize.</param>
        /// <returns>a valid PlusDomainsService</returns>
        public static PlusDomainsService AuthenticateOauth(string clientId, string clientSecret, string userName)
        {
            if (string.IsNullOrEmpty(clientId))
                throw new Exception("clientId is required.");
            if (string.IsNullOrEmpty(clientSecret))
                throw new Exception("clientSecret is required.");
            if (string.IsNullOrEmpty(userName))
                throw new Exception("userName is required for datastore.");


            string[] scopes = new string[] { PlusDomainsService.Scope.PlusCirclesRead,     // View your circles and the people and pages in them
                                             PlusDomainsService.Scope.PlusCirclesWrite,    // Manage your circles and add people and pages. People and pages you add to your circles will be notified. Others may see this information publicly. People you add to circles can use Hangouts with you.
                                             PlusDomainsService.Scope.PlusLogin,           // Know your basic profile info and list of people in your circles.
                                             PlusDomainsService.Scope.PlusMe,              // Know who you are on Google
                                             PlusDomainsService.Scope.PlusMediaUpload,     // Send your photos and videos to Google+

                credPath = Path.Combine(credPath, ".credentials/PlusDomains");

                // here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
                UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret }
                                                                                             , scopes

                var service = new PlusDomainsService(new BaseClientService.Initializer()
                {
                    HttpClientInitializer = credential,
                    ApplicationName = "PlusDomains Authentication Sample",
                });
                return service;
            }
            catch (Exception ex)

                Console.WriteLine(ex.InnerException);
                throw ex;
            }

        }
