On a Madone 6.2, I suggest using a torque wrench for
1. the steertube internal reinforcement plug
2. the stem at both ends (and tighten the bolts in rotation fairly gradually)
3. the seatmast cap clamping bolt (the external seatpost), which you might want to dose with carbon assembly compound, and the saddle-rail clamp bolt
4. your crankarm clamping bolts
5. your brake levers to your bar
6. your front derailleur to your frame, and go gentle... if the bolt's been greased, 25-30 inch-pounds can generate quite a lot of clamping force.
Also, be sure to put at least one headset spacer above the stem. This ensures that the stem's got 100% clamp engagement and isn't clamping onto the exposed end of the steer tube, possibly leading to stress risers and worse. Do this, use your torque wrench, and your backside's covered if there's ever a problem.
