You're on the right track. You should get your wheel as good as possible with regard to trueness, concentricity, tension and dish with the spoke tension very low. Then progressively increase tension while monitoring the aforementioned criteria. Fine tuning and stress relieving should be done at regular intervals as tension is increased.
