Answer 1

slight improvement on Pim Jager (guessing you want an array of the values returned):

function getCheckedNames(){
 var arr = new Array();
 var $checked = $('[@name=newsletter]:checked');
 $checked.each(function(){ 
  arr.push($(this).val());
 });
 return arr;
}

and with the improvement from duckyflip:

function getCheckedNames(){
  return jQuery('[@name=newsletter]:checked').map(function(){
   return this.value;
  });
}
