Для того чтобы отфильтровать список элементов инфоблока в компонентах bitrix:news.list или bitrix:catalog.section сделайте переменную фильтра глобальной.
$GLOBALS['filter'] = array("ID"=>array("12","13","14"));
Пример выводит элементы с ID равными 12, 13, 14:
$GLOBALS['filter'] = array("ID"=>array("12","13","14"));
