Your material -> maps -> opacity map.
Also, worldedit doesnt have ray tracing, all its gonna do is illuminate your plane accordingly, any mesh below it will receive light as if there is nothing covering it.

You can also use the alpha channel as well in your material if your texture has an alpha channel.
