I think as time goes on, there will be a lot more analysis on the subject. But in its current state, I really don't think it's worth the $$$ right now until they can reliably create a training plan focused around the power numbers.
I think there are enough canned training plans that you could basically pick from a menu of objectives and level of fitness. But in your case there are certain things that need to happen physiologically for your cycling fitness to catch up with your highly trained running ability. I'd guess, and there are some here who could tell you for sure, that you could set up a plan based on total stress to keep you from trying to get up to speed too quickly.
