Answer 1

Use something like the following (your code snippet was a little short)

$index = 1;
while ($product = $db->fetcharray($querySize)) {
    if ($index % 3 == 0) {
        //add your class here
    }
    $index++;
    //...

Answer 2

.

$count = 0;
while ($product = $db->fetcharray($querySize)) {
    echo "<li" . ((++$count % 3) ? "" : " class=\"right\"") . ">" 
        . $product['name']
        . "</li>\n";
}
