Answer 1

You can set ajax response like this:

 $response = array(
 'myblock' => $this->getLayout()->createBlock('module/admin_productqa_edit')->toHtml()
 );
 $this->getResponse()->setBody($response);

You can't use $this->_addContent or $this->_addLeft when doing ajax call because you are not loading entire layout object. You are supposed to process the response and update DOM with javascript.
