For Haskell, I'd strongly suggest Hutton's Programming in Haskell as an introductory text for folks with no functional-programming experience. First, it is slightly cheaper; and second, it has the word λ inscribed in large friendly letters (well, letter) on the cover. But seriously — it presents basic Haskell in a gentle but mathy way, without a lot of the gushing of some of the more recent texts. It's written as a textbook, with topics presented sequentially; with academic exercises rather than pseudo-industrial ones. Rather impressively, it presents Parser and IO monads before introducing the Monad abstraction by name, so one actually has worked some examples of monads before trying to puzzle out what a monad is.
