Sounds just like London
here is just a few ideas that might be worth trying.
Shooting RAW and JPG seems like a good idea, but in the menu increase the saturation and sharpness to give your jpg more punch.
Generally RAW is drap, just how it is, you need to add a bit in post processing.
The metering system in the 60D is the same as in the 7D, I think its pretty good in evaluative mode, suggest you leave it there. But maybe consider partial metering, this tends to work better for birds in challenging conditions, therefore may help with metering when focusing on a person.
Also set the focus to auto with centre or spot focus.
You can pretty well fix awb and other things if you play with the raw files, but not if its out of focus or motion blur. Also sounds like you need reasonable shutter speed, maybe use iso 400 or 800 or 1600 to stop motion blur.
Aperture depends on what you want to achieve but for people a larger aperture around 2.8 maybe better than F11. Use F9- F11 when you want more of the subject and background in focus, but don`t forget you are dramatically reducing the available light, so increase ISO to keep shutter speed up.
Also think of how affective some images may look in black and white, it doesn`t have to be rich in colour.
Oh and consider using the flash to light up the scene maybe even buy a flash.
