If you have never touched Haskell before, I would recommend reading the first 4 chapters of Learn You a Haskell[0] first. LYAH has a much more gentle introduction to Haskell, and really helped me grasp the basics.
After those chapters I would highly recommend working through Write Youself a Scheme, using LYAH as a reference when you need a more in-depth explanation of something. This is how I taught myself Haskell, but I realise that this approach might not work for everybody -- YMMV.
