Answer 1

Products in search and layer filtered navigation use the price index for displaying. As such you must reindex "Product prices" index.

Answer 2

Finally I found, the path

1. app\code\core\Mage\Sales\Model\Quote\Item\Abstract.php - function getPrice()
2. app\code\core\Mage\Tax\Helper\Data.php - function getPrice($product, $price.....)
3. app\code\core\Mage\Catalog\Model\Product\Type\Price.php - function getPrice($product)**

These All the files need to customize the price of the product
