Well I just fired up my computer with CS2 on it and ran through every possible way I could figure out, but it doesn't look like you can batch process an action from Image Ready and Image Ready actions won't transfer over to Photoshop. I can't even get Bridge to see the actions from Image Ready. The only thing that I can suggest is to make a droplet and use that.  It defeats the purpose of batch processing and puts you back in almost the same spot you started:( 

Sorry.
