Don't get that 15-85mm (and probably not a 5D mk II)

At least, I do not think that is the best idea. The f-values say something about how big the lens opening can be, and that a big impact on image look. The bigger the lens opening, the more shallow the depth of focus. Or in other words, while the subject is in focus, the back and foreground will get blurry.

To have a bit of control over this, it states that the bigger aperture the better.

The 15-85mm has a maximum fvalue of 3.5 at widest focal length to f5.6 at the long end. Not the best lens to fit the brief at all.

It would be wiser to look at the 17-50mm f2.8 class. Those lenses fit the brief much better.

The best one you can get besides the Canon EF-S 17-55mm f2.8 IS USM, but it is a tad expensive. SO I would recommend the just about as good Sigma 17-50mm f2.8 EX DC OS HSM. Together with the EOS 60D.

If for whatever reason you have people talk you into getting the 5D mk II, look at the Canon EF 24-105mm f4 IS USM or the very affordable and wider aperture Tamron 28-75mm f2.8.

Downsides for choosing a 5D mk II are:

It is big and heavy. Try one in a shop, it may feel not great in your hands if your hands are not big.
It has no built in flash.
The 60D has a very nice swivel LCD.

Lenses for the 5D mk II will always be heavier and more expensive. This may again be a problem.
The 60D has a better AF subsystem.

Plus points for the 5D mk II: With its bigger sensor, with the right lenses you have a bit more room for shallow depth of focus. And the bigger view finder.

I think it is a much smarter move to go for the 60D and the 17-50mm f2.8 from Sigma. Possibly with a canon EF 85mm f1.8 USM for bigger aperture portrait lens.

If in future you for whatever reason feel you want to grow into a full frame camera like the 5D mk II, you can always upgrade then. The prices of then 2nd hand 5D mk II's will have fallen to such an extent that it probably will cost less to own both the 60D + 5D mk II at that moment than a 5D mk II now.

The 60D is a very complete and good camera. Only get a more expensive camera once you know why YOU want it.
