Realviz has some nice programs that can help you with this. Matchmover
figures out camera tracking if I remember correctly. Image Modeller makes 3d
objects from photo's. Only thing is it's not free. I have a trial CD but you
can't save anything.

If the lens doesn't distort parallel lines it's just a matter of some
complicated trig and analytic trig...

Well the biggest problem I see is one of scale the buildings you rendered seem
too small for the one in the foreground.  If you want to see some really
impressive shots of this technique the fight club dvd has lots of how they did
it footage.  Many scenes that I thought were done with a camera were 3d
models.  What they did was take a real object, and take lots of pictures of
it, and then use them as image maps on a 3d model of the same object.  They
then had a completely believable 3d object that they could get impossible
camera shots of.
