No, unfortunately, Infinity-Ward announced that they are trying to promote present and new consoles like the PS3, XBOX360 and the Wii and will not be releasing Moder Warfare for the PS2.
Yes. War is very similar to Moder Warfare Two, hence the name. It is also extremely different to Modern Warfare, but I believe that I.W put those differences there on purpose.
