A join brings two tables together... For example for your needs:

SELECT <all the existing fields>,user.userid,user.username
FROM " . TABLE_PREFIX . "pf_product.createdby = user.userid
JOIN user ON pf_product

You'd work this into the query in the hook showthread_post_start

If you have a closed area of your forum for products play around with the code. While I understand it's not simple templates the best way to take control is by tweaking which leads to learning.
