Answer 1

You can get this by getRequest in getParam method of your custom controllers action like below

  public function massChangeTypeAction()
    {
      $orderIds = (array)$this->getRequest()->getParam('order_ids');        
    }

you can print this $orderIds to get selected order from grid

hope this will sure work for you.
