I would like to add a "Follow" on Facebook and Twitter button next to the Search bar.

Hi,

Simply adding the link into it in page.tpl.php (example):

<div id="authorize">
	<ul>
		<?php global $user; 
			if ($user->uid != 0) {
				print '<li class="first">' .t('Logged in as '). '<a href="' .url('user/'.$user->uid). '">' .$user->name. '</a></li>';
				print '<li class="last"><a href="' .url('user/logout'). '">' .t('Logout'). '</a></li>'; } 
			else {
				print '<li class="first"><a href="' .url('user'). '">' .t('Login'). '</a></li>';
				print '<li class="last"><a href="' .url('user/register'). '">' .t('Register'). '</a></li>'; }
				?>
		<li><a title="Dan on Facebook" href="http://www.facebook.com/danpros">Facebook</a></li> <!-- I add this -->
	</ul>
</div> <!-- end authorize -->
