Answer 1

These numbers are Frame rate counters. You can enable/disable them in App.xaml.cs:

// Show graphics profiling information while debugging.
if (System.Diagnostics.Debugger.IsAttached)
{
    // Display the current frame rate counters.
    Application.Current.Host.Settings.EnableFrameRateCounter = true;

    // other code…
}

Comment that line or change value to false to remove the counters.
