Well I have both a PS3, and Black Ops, but don't play CoD that much anymore. But if you want the map pack I'd suggest waiting for the new one (Resurrection I think). I also hear sharing map packs is a big no-no because you can get banned. Or you can wait for MW3 because I hear it's also gonna have zombies.
And while FF 7 is a good game imo, PS1 games kinda suck :O
