Answer 1

I did not went through all of your code, but what is immediately visible is that you should not override the paintComponent method without calling super.paintComponent. And your commented out line calls super.paintComponents (note the s), which is not the same.

I am also unsure what you mean 'when I resize the window', and how that is tied together with your Jpanel1.setSize( 1000, 1000 ) calls which appear all over your code. Your layout manager will take care of the size of the panel. You should not set that to a fixed size.
