1. No fees but you have to pay for PSStore games that you download but demos and movie trailers should be free
2. Updates are free, there is a system update on the XMB option, PSStore is were you download all the demos and trailers and buy the full arcade style games & PS1 games
3. Multiplayer gaming is free but expect lag I've read so if you have a good connection (ethernet/DSL and good ISP speed you should be fine)
4. You can I think but you can only download items from your registered countries address (IE. Italy)
5. Search for that since I don't have a PS3
6. You can but only PS3 Format titles, PS2 titles are region locked and so are DVD's (I'm not sure about Blu-Ray)
PS I don't have a PS3 just telling you what I know.
