Playstation Three news and reviews

I live in Ireland and hope to buy a Playstation 3 in the near future. I intend to play games online but I am not sure if my braodband connection is fast enough. I think my broadband speed is 2mb.

I'm getting a playstation 3 for my christmas (hopefully) and am wondering if it can play playstation 2 games?

Also if it can play normal dvd movies. I know it can play blueray an hd movies but can it play normal movie discs?

I am going to the USA next month and I have enough money to buy a Playstation 3 ( and tax etc…). I would like to know when i bring it back to the United Kingdom, will it work and I be able to play it? Even though the USA use NTSC and Britain use PAL?
