Answer 1

You can use :

$('#back-top a').click(function() {
  $('#nav > li.active').removeClass('active');
  $('#nav > li:first').addClass('active');
});

And add this CSS style :

li.active {
    background-color: #eee;
}

Regarding your needs (scrolling background on menu items), I really suggest that you take a look at : http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-lava-lamp-style-navigation-menu/
