I concur with Mark.
There's lots of info on custom sections floating around -- so I would search around a bit.
If you add a custom section as Mark outlined, then under Page Layout -> Custom Sections Position you choose "After the Page Header", that should be enough to do what you want without coding anything. You do not need to create a .tpl file for it.
Another way would be to add this in your fe_page.tpl file below your header and above your columns:
Code:
<div class="pagetitle">{{env:page_title}}</div>
Here you are using an insert tag to hard code the title of the current page into your template. (See: http://www.typolight.org/insert-tags.html).
