The only glaring problem I see with the code as posted is this line:
<h1>" href="<?php the_permalink() ?>" rel="bookmark">
should be this:
<h1><a title="Permanent Link to <?php the_title(); ?>" href="<?php the_permalink() ?>" rel="bookmark">
Otherwise…I had a terrible time getting my single pages to display properly with this theme, but it turned out to be the code in comments.php that was causing the problem.
Let me know if you’re still working on this and I’ll try to help you out.
