Answer 1

magento is stored customer_email in order table(sales_flat_order)

Now you can order list of order by using email id and but need fetch current customer email id then you can customer order list by below code:

$orderCollection = Mage::getModel('sales/order')->getCollection()
->addFieldToFilter('customer_email',$customerEmail)->addFieldToSelect('*');

foreach($orderCollection as $order){
    echo "<pre>";
    print_r($order->getData());
    echo "</pre>";
}

Answer 2

Please user the below code.

$orders = Mage::getResourceModel('sales/order_collection')
            ->addFieldToSelect('*')
            ->addFieldToFilter('customer_id',Mage::getSingleton('customer/session')->getCustomer()->getId())
            ->setOrder('created_at', 'desc');
