Magento change product name adding to cart - magento

Question

I want to change some values of some products while adding them to the cart in Magento CE 1.7
Im trying with the Observer checkout_cart_add_product_complete for this. Change the price (CustomPrice) works well if I try to change the product name or product images, its not saved.
Is there a way to change this attributes already on adding to cart?
public function checkout_cart_add_product_complete(Varien_Event_Observer $observer) {
[...]
// Set new Price
$lastAddedItem->setOriginalCustomPrice($originalProduct->getPrice());
$lastAddedItem->setCustomPrice($originalProduct->getPrice());
// Set Product-Name
$lastAddedItem->setName($originalProduct->getName());
// Set Product-Images
$lastAddedItem->setImage($originalProduct->getImage());
$lastAddedItem->setSmallImage($originalProduct->getSmallImage());
$lastAddedItem->setThumbnail($originalProduct->getThumbnail());
// Save updated Item and Cart
//$lastAddedItem->save();
Mage::getSingleton('checkout/cart')->save();
// Recalc Totals and save
$quote->setTotalsCollectedFlag(false);
$quote->collectTotals();
$quote->save();
Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
}

The function Mage_Sales_Model_Quote_Item::setProduct resets some of the basic information each time a product is saved (updated). Luckily there is an event "sales_quote_item_set_product" you can latch onto.
config.xml
<config>
...
<global>
<events>
<sales_quote_item_set_product>
<observers>
<samples>
<type>singleton</type>
<class>samples/observer</class>
<method>salesQuoteItemSetProduct</method>
</samples>
</observers>
</sales_quote_item_set_product>
</events>
<global>
...
</config>
Observer.php
class Mynamespace_Samples_Model_Observer
{
public function salesQuoteItemSetProduct(Varien_Event_Observer $observer)
{
/* #var $item Mage_Sales_Model_Quote_Item */
$item = $observer->getQuoteItem();
$item->setName('Ians custom product name');
return $this;
}
}
