Hi 2khaat !
for moving featured products module to under frontpage article you can do it following way below :
Open index.php file in templates/ja_mesolite folder , find following code section at about line 160 :
<?php if($this->countModules('vm-fp')) : ?>
<!-- BEGIN: FEATURE PRODUCTS -->
<div id="ja-topsl3">
<jdoc:include type="modules" name="vm-fp" style="xhtml" />
</div>
<!-- END: FEATURE PRODUCTS -->
<?php endif; ?>
cut it and paste to under following code below at about line 174 :
<?php if($tmpTools->getParam('showFrontPage') || !$tmpTools->isFrontPage()) : ?>
<div id="ja-content" class="clearfix">
<jdoc:include type="component" />
</div>
<?php endif; ?>
