To remove the postfoot on sticky posts, open index.php and look for:
<div class="PostFooterIcons metadata-icons">
<img height="18" ...
Posted in <?php the_category;?>
<?php comments_popup_link(...)?>
</div>
[Bear in mind that I've paraphrased a bit in the above]
Just before that block of code, add:
<?php if(!is_sticky()):?>
and just after, add:
<?php endif;?>
To remove the link on the header for sticky posts, look for:
<span class="PostHeader">
<a title="Permanent Link to <?php the_title(); ?>" rel="bookmark" href="<?php the_permalink() ?>"><?php the_title(); ?></a>
</span>
in index.php and replace with:
<span class="PostHeader">
<?php if(!is_sticky()) :?><a title="Permanent Link to <?php the_title(); ?>" rel="bookmark" href="<?php the_permalink() ?>"><?php the_title(); ?></a>
<?php else the_title();endif;?>
</span>
