As for the Shadow...

The Shadow seen in Shadow Vol 1 existed on Earth-One. We know this because he crossed over with Batman several times.

The Shadow seen in Shadow Vol 2 and Shadow Vol 3 existed in his own "Earth-Shadow" without any DC crossover.

The Shadow seen in Shadow Strikes Vol 1 also had no DC crossover, but he did share the universe with Doc Savage Vol 2, so I guess they had their own "Earth-Street & Smith"?

Don't know what's going on with the upcoming Batman/The Shadow miniseries, but it looks like they are establishing a Shadow on Prime Earth -- but we'll have to wait and see...
