Hi
I'm tryin' the CS6 and last month I've seen this interisting feature:
Copy tone color of picture to apply to another.
Like in this video.

Most of the features demonstrated at ADobe Max are still in development, but if you tell us exactly what effect you are after, I am sure people will do their best to help. For the B&W, there is already an excellent B&W adjustment layer in CS6, and you can use the drop down when the panel opens, and choose between a number of options. Or you can use the scrubby slider to drag over parts of the image to adjust their tonal values. There are also a number of third party plugins for B&W in Photoshop. I have never used any so can't comment on how good they are.
Cs6 has a new adjustment layer called Color Lookup which has some presets.
