If a wizards staff had no power in and of itself, then Gandalf's destuction of Saruman's would have been meaningless; saruman could have simply grabbed another stick of wood (Orthanc proably had a good pile of sticks to be used as firewood) or at least cut a new one (or had Grima cut him a new one) once he was let out (he proably wouldn't want to do so in Fangorn itslef (given how Ents react when you damage trees) but I'm sure there were other trees along the route he could have cut a new staff from. Moreover if the staffs had no power out of the wizards hands then way would aquiring all of them (i.e. "the rods of the five wizards) be a desirable goal?) I'm not saying that anyone who took a wizard's staff would be able to use magic, but the staff is probably, in a certain sense a part of the wizard and a wizard whose staff was destroyed or lost would find it diffcult, if not impossible to replace.
Speaking of replacing staffs I do agree that the staff gandalf carried into Moria was proably lost or destroyed in his battle with the Balrog. Indeed the penultimate line of Bilbo's tribute poem does say "his staff was broken on the stone" (though this may of course be only hobbit poetic imagery) when Gandalf was given his new life and his new flesh he presuably was given a new staff, more powerful than his old, as he now was.
