MGS4 has a database thingie in it which can tell you.
Though I strongly advise that you play the games before MGS4, particularly MGS3 which is probably the best non-Nintendo game besides the Phoenix Wright series in my opinion.
As for Twin Snakes, it's a remake of MGS1 that's exclusive to GC. It's the same as MGS1 in most ways, except the cutscenes are a bit more extreme. Oh, and of course, the graphics are better.
