nope. Your internet service could cost you money and a WiFi router or other equipment could cost you a one time expense, but unlike Xbox Live the Playstation Network is free. The only cost of the Playstation Network is purchases at the Playstation Store or for individuals who join Playstation Plus for Special Playstation Store discounts and other member benefits like an automatic update system for all your games and devices.
No, the demos are always free. Who'd ever pay money for a demo? People use demos to see if the full game is worth buying.
Most of the features of PSN are free to use. Online gaming, downloading demos, and PlayStation Home are all at no extra cost to you. There is a paid subscription to PSN called PlayStation Plus, and buying games and add-ons online cost money.
