Unlike snowboarding, ski bindings generally have little impact on actual skiing performance. They hold your boots to your skis and that's about it. You might want lighter bindings if you want to do tricks.
However, they are critical to safety. If the bindings don't work well at releasing your feet when you fall, the long lever of the ski can literally rip your knees to shreds and snap your bones like toothpicks. And the converse is true: if your bindings don't hold your boots solidly at critical moments and accidentally let go at an inopportune time, the results can be disasterous. I mean, imagine straight-lining on your board and suddenly you notice that you forgot to strap your boot back in. That could be bad, right?
That said, pretty much all bindings on the market work fairly well, assuming you've chosen one with the right DIN range. That's the tension setting specific to your stats.
I disagree about the approachability of the K2 Extreme. They're easy to ski, especially for somebody who isn't going to be starting with power wedges at 2mph. She's a board instructor, fer chrissake.
However, we're in complete agreement about the absolute unequivocal importance of getting boots that fit.
First thing, you must get boots that fit. This is a matter of seeing a reputable professional bootfitter, most likely at a resort town. This is a real point of difference from boarding: bindings don't matter much, but boots are everything.
