Answer 1

Please use this action url to get admin controller form action -

<form action="<?php echo Mage::helper('adminhtml')->getUrl('*/adminhtml_tracklink/your_form_action'); ?>" name="trackinglink" method="post">

Answer 2

Generally admin url's are working with secret code.

$url = Mage::helper("adminhtml")->getUrl("admin_trackinglink/<your_action_name>")

When we using above code. The secret key will automatically be added to the URL.

<form action="<?php echo $url; ?>" method="POST">

you give as first parameter a route with a controller, where the method is just waiting for a controller name.

DON'T USE anything else than adminhtml/ as start of the url, because magento 1.9.2.2 forbids everything else.
