Ooh, didn't know you had a PS3! I actually own the entire collection of the series just on my PS3 lol. It's all one huge story, so walking in blind will be weird if you only play one game since the story only unfolds more as you go deeper with the other games. Fans (including myself) still consider MGS3: Snake Eater as the best. Plus, it's perfect for beginners since it's the origin of the series.
