I’m in the “lightly grease the tapers” camp.

I use 30 ft-lbs for the crank arm bolts, and 40 ft-lbs for the DS of a sealed BB, confirmed as good middle of the range numbers for each location by Zinn’s manual. They’re the only places on a C&V bike where I use a torque wrench. I do use a small one on threadless stem bolts (typically @ 6 ft-lbs) of my wife’s modern-ish bike despite the steel steerer, since manufacturers seem picky about those bolts and they seem easy to over-tighten. I use Permatex silver anti-seize on all fastener threads, unless the component manufacturer has pre-applied blue Locktite.

BTW, on my own bikes, or those that I wrench upon frequently, I will re-torque those crank arm bolts to the same spec after about 50 miles. Then leave them alone!
