This is my recommended path for learning Haskell.
http://www.seas.upenn.edu/~cis194/lectures.html Brent Yorgey's course is the best I've found so far and replaces both Yann Esposito's HF&H and the NICTA course. This course is particularly valuable as it will not only equip you to write Haskell but also help you understand parser combinators.
While I love my Geeklets, I had a pretty hard time to set them up consistently across varying monitor setups (home, work, on the go,...). The bad news first: There is no built in mechanism (as of 01/2013) to take care of this problem. Still there are good news: With some minor tinkering, you can automagically position your Geeklets across multiple setups.
The initial step is to add your Geeklets - you can totally ignore the positioning for the moment.
