Hi Fredy
Try changing your Global Setting for your navigation (Articles -> Article Manager - Options and set 'Show Navigation' to 'Hide'.
To edit the Readmore text open your modules mod_j51hover.php and edit the following (..\modules\mod_j51hover\mod_j51hover.php)...
<a href="/<?php echo $hover_link; ?>" class="info">Read More</a>
Changing 'Read More' to your own taste.
