Answer 1

You should override the paintComponent() method, not the paint() method. Here is a link to the Swing tutorial on "Painting" which will explain why:
http://java.sun.com/docs/books/tutorial/uiswing/overview/draw.html
Don't forget to click on the "Working With Graphics" link on the bottom.
Here is a little program to get you started:
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
public class TestBackground extends JFrame
     ImageIcon img;
     public TestBackground()
          img = new ImageIcon("????.jpg");
          JPanel panel = new JPanel()
               public void paintComponent(Graphics g)
                    g.drawImage(img.getImage(), 0, 0, null);
                    super.paintComponent(g);
          panel.setOpaque(false);
          panel.add( new JButton( "Hello" ) );
          setContentPane( panel );
     public static void main(String [] args)
          TestBackground frame = new TestBackground();
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setSize(300, 300);
          frame.setVisible(true);
