Thanks for the help. Although that didn't work, I was able to successfully achieve with the following code...just changed the path of Mage.php according to my setup:
require_once 'app/Mage.php';
umask(0);
$app = Mage::app('default');
$app->getTranslator()->init('frontend');
if( ($_COOKIE["frontend"]=="") || ($_COOKIE["frontend"]=="undefined") || ($_COOKIE["frontend"]==null) )
{
$session = Mage::getSingleton('customer/session');
session_name('frontend');}
else
{session_name('frontend');}
Mage::getSingleton('core/session', array('name' => 'frontend'));
$className = Mage::getConfig()->getBlockClassName('checkout/cart/sidebar');
$block = new $className();
$block->setTemplate('checkout/cart/sidebar.phtml');
$cart = Mage::helper('checkout/cart')->getCart()->getItemsCount();
$carturl = Mage::helper('checkout/url')->getCartUrl();
echo $block->renderView();
echo '<br />cart items count: <a href="'.$carturl.'">' . $cart."</a><br />";
echo "cart Summary Qty: ".Mage::helper('checkout/cart')->getCart()->getSummaryQty()."<br />";
$cart_count = Mage::helper('checkout/cart')->getCart()->getSummaryQty();
