To prevent spidering by bots you can add code to the products_detail.php and products_results.php page and add: <META NAME="ROBOTS" CONTENT="NOINDEX"> into the header.
Until we release an update to resolve this issue, the only way to get a unique title, keyword, and description would be to add those three columns to the products table in your database and add three fields where they can be edited onto the admin/products_insert.php and admin/products_update.php pages. Then you could use those values to create unique meta-tags and titles.
