I was going to recommend Sludge Bomb for Crobat. Good job in knowing the value of a typically underrated Pokemon. Other than that, I really don't know. I don't worry too much about maximizing stats and items; I know that if I train my Pokemon enough, then I can overcome even the most devastating type disadvantages (except, of course, in cases such as Psychic vs. Dark, Poison vs. Steel, Ground vs. Flying, and Normal vs. Ghost [and vice versa]).
