Answer 1

Your method should return a list of select items from your method.
Following example populates a select items list by using an ArrayList.
public List<SelectItem> getUsers(){     
     List <SelectItem> usersSelectList = new ArrayList<SelectItem>();
     List<User> usersList = userService.getUsers();
     for (User refUser : usersList) {
          usersSelectList.add(new SelectItem(refUser.getFirstName(),refUser.getFirstName());
     return userSelectList;
}
