Answer 1

This can be achieved through converter which do the work of finding if its last item in the listbox -

Converter

public class IsLastItemInContainerConverter : IValueConverter
{
   public object Convert(object value, Type targetType,
                         object parameter, CultureInfo culture)
   {
       DependencyObject item = (DependencyObject)value;
       ItemsControl ic = ItemsControl.ItemsControlFromItemContainer(item);

       return ic.ItemContainerGenerator.IndexFromContainer(item)
               == ic.Items.Count - 1;
   }

   public object ConvertBack(object value, Type targetType,
                             object parameter, CultureInfo culture)
   {
      throw new NotImplementedException();
   }
}

And using that you can set the DataTemplate in your xaml class like this -
