In the messages you posted above, one said "transaction did not validate". That means that the info from paypal didn't match anything found in your zen cart database for pending paypal transactions.
All the things that are posted in the setup/troubleshooting guide in the wiki ( http://www.zen-cart.com/wiki/index.php/PayPal ) are related to how the whole infrastructure works.
Numerous bugs were fixed between v1.3.0 and v1.3.5. Upgrading will be very worthwhile.
