Attention!
What this code does is: every time the magento-cronjob removes all sent messages from the core_email_queue database table, it also removes all recipients of these messages. So, basically, it does not work for you until this cronjob-task has run at least once.
Solution
I found the answer thanks to another question here: the core_email_queue_recipients table was not emptied by the cronjob. The method Mage_Core_Model_Email_Queue::cleanQueue() calls Mage_Core_Model_Resource_Email_Queue::removeSentMessages(), which is pretty simple:
public function removeSentMessages() {
$this->_getWriteAdapter()->delete($this->getMainTable(), 'processed_at IS NOT NULL');
return $this;
}
Anyway, this method does not remove the old recipients. Thus, as soon as a new message with message_id n is queued, all old recipients with message_id n will also get the new email. The thing I don't understand is: why has the core team not seen this, and why doesn't this lead to more issues?
I wrote a small module to fix this. It uses a class override for Mage_Core_Model_Resource_Email_Queue, so if anybody can suggest a better (event-based?) solution, I would be glad.

You can fire a JS click method after page load like
<script type="text/javascript">
//<![CDATA[
jQuery(function($) {
$('input[name="shipping_method"]').get(0).click;
});
//]]>
You can use the same thing on specific element id of Ground

I would suggest that you could look into using the payment type invoice. Here you can send an invoice to the customer when you want it and include all the needed information regarding payment information.
I have used the Itabs_Invoice extension for this in the past and it works very well.
