How is good way to use hooks

Generally, don't we use:
<?php
$this->load->view("vwHeader");
?>
..........
<?php
$this->load->view("vwFooter");
?>[/quote]
Agreed ! actually its simple way to do that. If the header and footer are not static and vary from page to page then we can call them in controller as partial or using parser.
