Good advice.
My criteria for HTII crank installations is to carefully insert the spindle after installing the bb cups snug but not fully torqued. If the spindle lines up accurately with both cups, I'm satisfied the bb shell is faced properly. If you have to force the spindle to align it with the second cup, the shell need to be faced. So far, all the bikes I've installed them on (3 Litespeeds and a Surly Pacer) have let the spindle line up perfectly and no facing was required.
I also use a torque wrench on the nds crankarm pinch bolts. Tighten the two bolts in sequence approaching the final torque (~100 inch-pounds) in stages.
