<?php
$cart = Mage::getModel('checkout/cart')->getQuote(); //to get cart detail
foreach ($cart->getAllItems() as $item) {
   echo  $productId = $item->getProduct()->getId(); // product id in cart
   echo $productPrice = $item->getProduct()->getPrice(); // product price in cart
$product = Mage::getModel('catalog/product')->load($productId); // load product to get all details of product
//load the categories of this product
$categoryCollection = $product->getCategoryCollection();
$catIds = $product->getCategoryIds(); // to get all category ids of products in cart
$catCollection = Mage::getResourceModel('catalog/category_collection')  // to get all all details of categories of products in cart
                     //->addAttributeToSelect('name')
                     //->addAttributeToSelect('url')
                     ->addAttributeToSelect('*')
                     ->addAttributeToFilter('entity_id', $catIds)
                     ->addIsActiveFilter();

foreach($catCollection as $cat){
 // print_r($cat->getData());
 $catname[] =  $cat->getName();
  //echo $cat->getUrl();
}
