Archer has it generally, you just need to specify that as a submitHandler within the validate call:

$("#commentForm").validate({
    submitHandler:function(form){
        if (this.valid()){
          $('#submit').addClass('next');
          form.submit();
        } 
    }  
});

Here it is in action: http://jsfiddle.net/ryleyb/kKSjL/1/
