Answer 1

You have to set date format as per your current locale

$dateFormatIso = Mage::app()->getLocale()->getDateFormat(Mage_Core_Model_Locale::FORMAT_TYPE_SHORT);
        $fieldset->addField('not_allowed_date', 'date', array(
            'name'   => 'not_allowed_date',
            'label'  => Mage::helper('po')->__('Not Allowed Date'),
            'title'  => Mage::helper('po')->__('Not Allowed Date'),
            'image'  => $this->getSkinUrl('images/grid-cal.gif'),
            'input_format' => Varien_Date::DATE_INTERNAL_FORMAT,
            'value' => date('d/m/Y'),
            'format'       => $dateFormatIso
        ));

To Display Current Date in date picker you need to set date in value parameter

    $fieldset->addField('not_allowed_date', 'date', array(
               'name'      => 'not_allowed_date',
               'label'     => Mage::helper('catalog')->__('Not Allowed Date'),
               'required'  => true,
               'image'  => $this->getSkinUrl('images/grid-cal.gif'),
               'format' => 'dd-MM-yyyy',
               'note' => "dd-mm-yyyy",
               'time' => true ,
               'value' => date('d/m/Y')
               )
   );
