im a bit confused with the post so hopefully this will help you, if not then let me know.
I think the problem is that in your renderer your saying
setBackground(header.getBackground());which is setting the backgound of the renderer rather than the selected item, please see an example below, I created a very simple program where it adds JLabels to a list and the renderer changes the colour of the selected item, please note the isSelected boolean.
Object "value" is the currentObject its rendering, obviously you may need to test if its a JLabel before casting it but for this example I kept it simple.
populating the list
public void populateList(){
        DefaultListModel model = new DefaultListModel();
        for (int i=0;i<10;i++){
            JLabel newLabel = new JLabel(String.valueOf(i));
            newLabel.setOpaque(true);
            model.addElement(newLabel);           
        this.jListExample.setModel(model);
        this.jListExample.setCellRenderer(new RowHeaderRenderer());
    }the renderer
class RowHeaderRenderer extends JLabel implements ListCellRenderer
    JTable theTable = null;
    public Component getListCellRendererComponent(JList list, Object value,
                                                  int index, boolean isSelected, boolean cellHasFocus){
        JLabel aLabel = (JLabel)value;
        if (isSelected){
            aLabel.setBackground(Color.RED);
        }else{
            aLabel.setBackground(Color.GRAY);
        return aLabel;       
}
