So using the supplied link and picture file I tried a little pp myself. I think I understand what you are going for and I tried to replicate that. (I hope you don't mind. If you do, I will remove it.) Please note that this may have turned out a little better had I used the original file. Actually I am sure it would have.

Focus is alot of it, depth of field an equal part, white balance and tone I think can be done in post processing. I ran this through Lightroom 2.3, followed by CS4. In CS4 did an unsharp mask, followed by a light spot gradient with a bit of a lens blur. Nothing fancy, just trying to replicate what I think the lens should have done.
