I would stick with Campy all around. Sram doesn't come in a triple and only 10 speed rear. With campy you can do multi-shifts in each direction on the rear. The front does take getting used to. You have to completely unload the drivetrain to shift cleanly....which means telling the stoker to stop pedaling. The first few times out I would overshift past a "ring."
In hilly areas, you need the range. We were topped out in the "60."
We have the steel fork with V-brakes. I thought about getting a carbon fork but with the 28mm tires, it's pretty smooth. I might add some gel tape to dampen it more if I think it's needed. Carbon would save weight.
One other thing is paint. Ours has a really cool paint job, pretty similar to:
