Answer 1

You have to use selectitem list in the f:selecitems attribute of h:selectOneMenu

Your page will be like this;

At the backing bean side you have to fill the studentSelectItemList selectitem.

private List studentSelectItemList;

//fill studentSelectItemList at the appropriate place
  studentSelectItemList.add(new SelectItem(studentId,studentName));

After these settings you should have student id as select value.
