Good stuff. I would add that one exercise which should really help is sitting down and actually quantifying the value customer receives - dollars saved, dollars earned, time saved, all broken down by type of customer (however you chose to define that), and by the aspect of their workflow you aim to improve. What this will do is anchor your pricing gu feel to the right range. Besides, you can show it to the users and get valuable push back where you're off. My mentors spent countless hours convincing me of the value of this exercise and it's finally sinking in now, so I am in a hurry to share the wisdom. :)
