How do I change the order of the pieces when a story is in a book with an attachment

I've started a site using 4.7 beta 4. But this is the same in 4.6.

I created a story. The story has an attachment. I then added the story to the outline of a book. The resulting page places the book navigation in between the body text of the story and the attachment list. It makes the attachment look like a separate item from the story itself.

How do I change the order of these items?

In node.tpl.php, I have:

<?php if ($page == 0) { ?><h2 class="title"><a href="/<?php print $node_url?>"><?php print $title?></a></h2><?php }; ?>
    <span class="submitted"><?php print $submitted?></span>
    <span class="taxonomy"><?php print $terms?></span>
    <div class="content"><?php print $content?></div>
    <div class="links">&raquo; <?php print $links?></div>

So it appears to me that $content is the source of the body text, the book navigation and the attachment list. I don't want to hack up the book.module, upload.module or node.module.

Is there another way to control this order?

If I remove $content from node.tpl.php and add in the pieces myself, what will I miss in not having $content in my node.tpl.php?

Anyone have a suggestion or direction for me to explore? I still have a lot to learn with Drupal and PHP but I'm evolving. :)

Thanks in advance for any help...
