Appearances>Menus> See if it gives you options. I edited that theme once. I widened the sidebar.
maybe go into menus and remove the names,
or look for this in the theme files – <div id=”top-bar”>
<div id=”header”>
<div id=”nav”>
<div id=”header-menu-wrap” class=”clearfix”>
<div class=”clear”></div>
get rid of this – <ul id=”header-menu” class=”menu clearfix default-menu”>

I know that may have sucked as far as my explaining. But you need to go into the theme files, and kill off the specified html.
You will not be able to access the files from wordpress, you will need to hit the host files.
