I am using $request = $observer->getRequest();in my observer method but it is not returning anything. i am using sales_order_place_beforeevent.

To get Request parameters in the Observer, use following code

Mage::app()->getRequest()->getParams();

To get post variable

Mage::app()->getRequest()->getPost('your-param');

you can get shipping and billing array with below code

$shipping=Mage::app()->getRequest()->getPost('shipping');
$billing=Mage::app()->getRequest()->getPost('billing');
$yourfieldname=Mage::app()->getRequest()->getPost('yourfieldname');

Use the following code to resolve your query:

public function yourFunction(Varien_Event_Observer $observer)

 $order = $observer->getEvent();
 echo $order->getOrder()->getPayment()->getMethod(); // get selected paymante method

 $quote = Mage::getSingleton('checkout/session')->getQuote();
 echo $quote->getBillingAddress()->getTelephone(); // get billing address phone number

You may also try with below code to read all the parameters

 $orders = $observer->getData();
 echo '<pre>'; print_r($orders); echo '</pre>';

As you can see from Mage_Sales_Model_Order::place(), the only available data for this event is order. To access the request object inside your event observer, you can do something like:

$request = Mage::app()->getRequest();

public function yourFunction(Varien_Event_Observer $observer)

 $order = $observer->getEvent();
 echo $order->getOrder()->getPayment()->getMethod(); // get selected paymante method

 $quote = Mage::getSingleton('checkout/session')->getQuote();
 echo $quote->getBillingAddress()->getTelephone(); // get billing address phone number
