Ok, it seems like u’ve messed up a bit. Let’s see if I can help you:

lines 105-107 replace with:

$query = new WP_Query('cat=12&showposts=5');
while($query -> have_posts()) : the_post();

You could include all this while->endwhile within if->endif but lets assume query will return any posts for now.

then at line 118 insert missing endif (from thumbnail check)
<?php endif; ?>

File should be fixed after that. As for next previous links. By default wordpress does it like this:

<?php previous_post_link( '%link', __( '<span class="meta-nav">←</span> Previous', 'twentyeleven' ) ); ?>
<?php next_post_link( '%link', __( 'Next <span class="meta-nav">→</span>', 'twentyeleven' ) ); ?>

Didnt dig too deep into that links but u can check WP documentation for details:

I am having the same issue(wp 3.2.1, tinyMCE 3.4.2.1 – tried previous verions as well). No table outline and no borders for columns in edit mode as it used to be.

Also one more thing I am having problem with is: If there isn’t anything preceding the table there is no way I can remove it from editor window(can’t select and delete it etc. – only through HTML editor or Ctrl + A –> del)
