Answer 1

You can specify BorderBrush and BorderThickness for the DataGridColumnHeader. Example

<DataGrid.Resources>
    <Style TargetType="{x:Type DataGridColumnHeader}">
        <Setter Property="Background" Value="Blue"/>
        <Setter Property="BorderBrush" Value="Red"/>
        <Setter Property="BorderThickness" Value="1,1,1,1"/>
    </Style>
</DataGrid.Resources>
