You can change the placement of the navigation page numbers (and add more to the top of the page layout) by creating a template override.
For instance, if you want to change the appearance of the page number links on the Article Category Blog layout (with the default sample data, this is the "The News" item in the Main Menu), you will make a copy of
joomla_root/components/com_content/views/category/tmpl/blog.php and save it as
joomla_root/templates/your_template/html/com_content/category/blog.php.
Next open the file you just created and look for
Code:
<?php echo $this->pagination->getPagesLinks(); ?>
This is the specific code that causes the pages links to display.
You'll notice that it is surrounded by php logic that checks whether the parameter 'show_pagination' is set to Yes. And it is important that this whole block is used if you want to display another instance of the page numbers navigation at the top of the page.
Code:
<?php if ($this->params->get('show_pagination')) : ?>
<tr>
<td valign="top" align="center">
<?php echo $this->pagination->getPagesLinks(); ?>
<br /><br />
</td>
</tr>
<?php endif; ?>
More info on the pagination elements that can be used in your template is available in the Documentation Wiki
