Now the PS2 is a different entity entirely, you'll be pleased to know
- well you wont as it's bad news
The PS2 is region locked, so if you brought it over from the US your current games would work but you wouldn't be able to buy any new ones.
Power wise you should be fine with just a plug convertor (yay sony!)
Any newer TV should be able to handle it fine, if you have an older TV it may show up as black and white or distorted due to the different refresh rates between NTSC and PAL.
Generally with a PS2 you have a couple of options.
Sell it and your games and buy a new one - you can get a phat PS2 for about £30 and a slim PS2 for about £50, I've got a boxed slim PS2 if you want one
Bring it and just play the games you already have and import any extra games you want
If you're handy with a soldering iron, buy a modchip, mod it and you can play any games
If you have a Phat PS2 you should be able to soft mod (i.e without soldering) it, there's kits about. If it's a slim and lite PS2 you'd need to solder it.
Buy a 60 gig Backwards compatible PS3 in either country (or a 80gig gunmetal grey Metal gear solid SE PS3 if you can find one) (they don't make these any more so it will be second hand.)
