Play the first game first. People shit on the dub, but it won't annoy you if you don't get used to the original, so it's another reason to not leave it for later. And it is a good game. You shouldn't skip any of them.
I own the other games, but I pirated 1 and 2 before I played 3. Pirating 2 on the PS2 had some complications because the original disc has two layers and is kinda weird overall, so you can't just burn it all in a dual layer DVD. It doesn't work, but there is a way to solve it by splitting the game in two and recording the second layer separately, and that allows you to continue to play the game after it freezes.
You should also play Kiwami. Play all of them. Wish I could play the ones that are only available in Japanese.
