Page title not displayed at the top of the Content area The page title is displayed in the breadcrumb, but not as a page title, at the top of the content area. Is there a setting somewhere I can edit, or will I need to manually add it to node.tpl.php?

The Title field is there, in the Content type - manage fields.

The search results page however, does have the page title displayed at the top of the content...(?)
According to your node.tpl.php, if the node is viewed in teaser mode, that $title variable will be output. (if (!$page):)

For the node view in full page mode (if ($page == TRUE):) then you need to have print $title in your theme page.tpl.php

i.e:

  &lt;?php print render($title_prefix); ?&gt;
  &lt;?php if ($title): ?&gt;
    &lt;h1 class="title" id="page-title"&gt;
      &lt;?php print $title; ?&gt;
    &lt;/h1&gt;
  &lt;?php endif; ?&gt;
  &lt;?php print render($title_suffix); ?&gt;
