Working through Learn You A Haskell is a good start.

After that, I honestly think you'll get the best bang-for-buck by reading library-specific tutorials. If you play with enough of the libraries the rest of the language more or less falls into place.

Conduit is a pretty ok streaming library, and has good documentation: https://github.com/snoyberg/conduit#readme

Lens gives you a lot of useful features that more or less correspond to stuff like Getters and Setters in something like Java, and the tutorials for it get into some helpful details about writing Haskell code: https://hackage.haskell.org/package/lens

Otherwise it's basically a lot of "just build shit, and don't be afraid to feel confused" and it'll fall into place.
