Maybe the servers are down.
You don't download the Playstation Network you connect to it by signing in from your PS3
In order to connect to the Playstation store you must sign in to the Playstation Network and select the icon from the Xmb for the Playstation Store.

No. Live is a term for the Xbox and the Playstation Network is what PSP and PS3 users have for online games and more. There are no PS3 Live servers only because Playstation has the Playstation Network and Xbox has Live PS3 is owned by Sony, and they have their own servers. XBox is owned by Microsoft.
NO you can not. A PC Emulator includes a PS2 Bios so it could not be called solely on a computer. Not that I know if you can use it to get on the Playstation Network. Any PC can access the Playstation network that is available for the PC and it is not the online games section that is available, but the support section. A PC could not even play a PS3 game and the Playstation Network would not work with a PC game as they are not compatible.
yes it can be.
No no no
Playstation Home will only be available to members of the Playstation Network and will not be available to everyone
The only subscription fee is for PlayStation plus which is not needed for the PlayStation Network and mostly concerns bonuses available from the PlayStation store.
Connect your PS3 to the internet then log into PlayStation network
yes it can as long as you update it
