3) aperture: when it gets dark, you will want something in the f/2.8 or even a f/2.0 or better prime lens, such as the 99$ 50mm f/1.8.
Not necessarily true. In the dark, if you can use a tripod or otherwise keep the camera perfectly steady and reduce the camera speed, a f/2.8 aperture isn't a must have since an immobilised camera on a low shutter speed can let in sufficient light. The benefit of a large aperture where no amount of trickery with a smaller aperture can give the same result is that you can attain a lower depth of field so the subject needn't be as far away from the background so as to keep it out of focus while only the subject remains in focus.
I would agree with you if you're shooting a statue in the dark, but if you're shooting people or other moving things, 1/30 sec is pretty much the very slowest shutter speed you can get away with, in which case you'll need a fast prime or a flash to compensate. Of course if you had the budget for a D4, D800, or 5dIII, then you could just crank up the ISO, but that's a story for another thread
