No. There's no monthly fee for regular PSN usage, however there is a PlayStation Plus membership which has a subscription fee.
It is not the Playstation 3 network that you can get a free month of. The Playstation Network is free. What you can get free is a 30 day membership in Playstation Plus when you purchase a new PS3. It is not that much of a benefit as you can get a full year of Playstation Plus for only $50 or $18 for a 3 month trial. Playstation Plus gives you discounts and free offers from the Playstation Store and is not needed for any online game playing. PSN + also has an automatic update feature for the PS3 and the games so you never have to wait while the system or game is updated before you play
