*facepalm* That's not what he was asking. Those are the update packages. That's not gonna do jack without having the original 2.0 files installed.
OP, the best you can do is obtain a Leopard DVD from a friend or by "other means". I highly doubt they'll do it but maybe you could take it into the Apple store and they could grab a spare Leopard DVD to install them for you, but this would be a kind gesture on their part so it probably won't work.
