As important than the final torque, if not more so, is the sequence of tightning, and keeping both upper screws and both lower matched as pairs. When kept matched each screw does half the work, but if not matched it's easy to over tighten or stress the tighter bolt.
As far as the torque wrench goes, I'm more a believer in calibrated fingers and awareness of how the torque is ramping up as I come to working tightness. Also keep in mind that some stems that don't have thread inserts will have lower torques limits than you'd expect based on screw diameter.
