I honestly thought that the bridge was where the camera is sitting in this shot:

And as for the who is standing where and at what window, nothing ever seemed off to me. I am ashamed to call myself a Star Wars fan. I bow to all of your superior nerddom.

I thought that this area was behind the bridge and could be accessed from either side (like a horseshoe shape behind the back wall with an entrance on either side).

That would explain how Vader got to the other side but I'm loving the new shots anyway.
