Hey,
1) To remove the search box open up header.php and delete following code:
<div id="headextras" class='rounded'>
<?php get_search_form(); ?>
<ul class="social_bookmarks">
<?php if(isset($k_option['general']['contact_link']) && $k_option['general']['contact_link'] != '')
{
$contact_link = get_page_link($k_option['general']['contact_link']);
echo "<li class='email'><a class='ie6fix' href='".$contact_link."'>E-mail</a></li> ";
}
?>
<li class='rss'><a class='ie6fix' href="<?php bloginfo('rss2_url'); ?>">RSS</a></li>
<?php if(isset($k_option['general']['acc_tw']) && $k_option['general']['acc_tw'] != '')
echo "<li class='twitter'><a class='ie6fix' href='http://twitter.com/".$k_option['general']['acc_tw']."'>Twitter</a></li>";
?>
<!-- there is room for 3 icons, below are predefined classes for others if you want to use them instead -->
<!--
<li class='flickr'><a class='ie6fix' href="#">flickr</a></li>
<li class='facebook'><a class='ie6fix' href="#">Facebook</a></li>
-->
</ul><!-- end social_bookmarks-->
<!-- end headextras: -->
</div>
If you want to keep the icons (and the black box around the search form) delete just following line:
<?php get_search_form(); ?>
2) To increase the header height open up style.css and search for following code:
#head{
z-index: 5;
position: relative;
width:960px;
margin:0px auto;
padding:0 20px;
height:200px;
}
Adjust the height value (200px) as you like.
