p3.add(ta);
setLayout(new FlowLayout(FlowLayout.CENTER)); // this overides everything, why?
add(p3);

Answer 1

menuSelected is a Abstract method. That means if you implement the MenuListener Class you SHOULD define the menuSelected() event.
I am not correct with the Method names but logically it seems that tis is the problem.
Another thing, use setJMenuBar() instead setMenuBar()
