Answer 1

I use the removeBackEntry method on the NavigationService Class. I also use this as a way to setup my own splash screens

        private void BWorkerRunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
    {
        // switch screen 
        NavigationService.Navigated += new NavigatedEventHandler(NavigationServiceNavigated);
        NavigationService.Navigate(new Uri("/Pages/main.xaml", UriKind.Relative));

    }

    void NavigationServiceNavigated(object sender, NavigationEventArgs e)
    {
        NavigationService.RemoveBackEntry();
    }
