I would definitely start with learn you a haskell. It makes a much better introduction to the language than RWH. RWH is great when you have learned the basics and want to start tackling bigger problems. Xmonad is a pretty common recommendation for looking at "good haskell code", in particular the overall design and how they keep the IO part minimized and isolated so the bulk of the application is easier to unit test. I think the standard libraries the come with GHC are good examples too.
