Have a look at the code below:

<?php
    $mageFilename = 'app/Mage.php';
    require_once $mageFilename;
    Mage::app('default'); 
    $collection = Mage::getModel('catalog/product')->getCollection()
    ->addAttributeToFilter('manufacturer', '3')
    ->addAttributeToSelect('*'); 

    foreach ($collection as $product) {
        $product->setName('NEW PROUDUCT NAME');
        $product->setCenaBaleniaCzk(999);
        $product->setCzk('NEW Czk VALUE');

        $product->save(); // This line is extremely important to commit your changes
    }
?>
