PS3 Game + Misc Qns.

First, the misc qn.

I have a broadband at home, which i'm currently using for my PC. So, i'm getting ready for my New PS3, and I was wondering If I am able to use my Broadband for the PS3 and my PC, If yes, how am I suppose to do it.

The PS3 Game Qn,

Its regarding Guitar Hero III: Legends Of Rock. I know that there are downloadable songs for Gh3, and I was wondering if the downloadable songs are free on the PS3, or would i need to pay with some kind of currency?

You can hook your PS3 up to the internet using either a wireless router or through a hardwired connection with no problems.

Yes, you need to pay for extra GH content using either a credit card or debit card.

You can also pay with a prepaid PSN Card if you can find one. They're pretty hard to find though.
