Answer 1

return false from the submit handler

submitHandler: function(form) {
    $(form).ajaxSubmit();
    return false;
}

Answer 2

This is my solution, put it after invalidHandler :

            submitHandler: function(form) {
                var dataString = $('#YourFormID').serialize();
                $.ajax({
                    type: 'POST',
                    url: 'yourpage.php',
                    data: dataString,
                    success:  function() {
                        $('#YourErrorDivID').hide();
                        $('#YourSuccessDivID').html("Your Message").show();
                    }
                });
            }
