About the whole plan thing... you have to remember things don't always go as planned. And yes, sometimes they can be useful and help relieve stress from the future possible situation, but you never know what will happen. Its a good plan, yes, and if it works out exactly like that, it will be good. Just don't get discouraged if it doesn't go exactly like that.
I myself am an avid planner, I have a plan for any situation that may pop up. But for me, the best conversation and encounters happen when they are spontaneous. When my plans do work out, they seem stale to me.
But i hope everything works out for you! =]
