95% torque for take off, and then maintain 90% through the climb (you can push 100% up to FL260). For cruise use the torque you like without exceeding 250 kts or M.67. Start your descend earlier than what the FMC suggests, or set on the DESCEND page a descend angle of 2*. You must keep some torque (do not descend on idle) to keep oil warm.
