Hi,
You shoule separate your questions in to different threads so that it would be helpful if others have the same concern.
For the 1st one, if you use the Inspect Element editor in browser, you can see that the blue block belongs to the 'header' block of template and the white is from the ' mainnav' block: http://prntscr.com/kbzk0i
Check the layout you're using and open the accordingly layout file in this path: root/templates/ja_social_ii/tpls/
and swap order of these 2 lines:
<?php $this->loadBlock('header') ?>
<?php $this->loadBlock('mainnav') ?>
Regards
