Answer 1

Try this Binding="{Binding RelativeSource={RelativeSource Self}, Path=UserName}"

Answer 2

You'll need to set the DisplayMemberPath on your ComboBox to be the property on the underlying object you want to see in the ItemsControl

If this is not specified, and you have not overridden the ToString() method on that object, you will just see (what you are now seeing) - the qualified name of the object.
