Answer 1

According to your example, the shipping title may or may not be derived from the database. Thus, the collection cannot be created directly. It should still be possible to create your collection afterwards – once you have all necessary data at hand:

$methods = Mage::getSingleton('shipping/config')->getActiveCarriers();

$shipMethodCollection = new Varien_Data_Collection();
foreach ($methods as $shippingCode => $shippingModel)
{
    $shippingTitle = Mage::getStoreConfig('carriers/'.$shippingCode.'/title');
    $shipMethod = new Varien_Object(array(
        'code' => $shippingCode,
        'title' => $shippingTitle,
    ));
    $shipMethodCollection->addItem($shipMethod);
}
return $shipMethodCollection;
