Any rubber/urethane bushings you want to torque them down when they are at their natural center. The bushing is designed to flex back and forth as the parts rotate, and it only flexes so far before it will tear.
If you torque a bushing down with the vehicle jacked up and the suspension just hanging, then you torque the bushing down at one extreme. It will be at max flex when you load of the suspension and rotate the suspension parts to their normal position, (where the bushing should be at little flex) then when you go over a bump and rotate the suspension parts the opposite direction than when it was hanging off the frame, which flexes the bushing even farther than it was designed.
Attach all the points, but don't torque them down until you have the car resting like it was parked in the parking lot (that includes steering wheel centered).
I would use a torque wrench if you have it.
