[LOTR] Is Saruman actually any more powerful with two staffs than one?

For that matter, does he need it at all? I figured his powers like telekinesis/telepathy/weather control would be innate.

Not really, no. He was depriving Gandalf of his own power. And even then, turning to Sauron's side (or, in the books, rejecting his title of "The White" in place of his own made-up "The Many-Coloured") caused him to fall out of favor with Eru who stripped him of his power.
