Also - keep a little list of the "festering" questions you have - then after a while (little too early yet, I think) - ask him if he can set aside some time for you to ask a few questions you need to clear up. Then go through your list very unemotionally, and TELL him what you would like him to do to make it better (no point in just ragging on him for a bunch of past stuff he can't change.)
