As for [1], create a file index.php in your
"health" folder with just "<?php echo "hello world";
?>" and go to
http://health.jbdirectory.com/ if you see the "hello
world" message, it probably means [1].

You can just place in such index.php
define( 'LOCALSETTINGS', dirname( __FILE__ ) . '/LocalSettings.php' );
chdir('../common mediawiki');
require 'index.php';
And in the LocalSettings at common mediawiki folder:
require 'LOCALSETTINGS';
