DrScheme (included with PLT-Scheme) is best for learning Scheme IMHO - the different language packs are really helpful, the stepper is AMAZING (using the stepper was the only way I was able to grasp/see a continuation and collector in real time). Emacs is my primary programming environment but thus far DrScheme beats Emacs with it's visual debugger and stepper - it is perfect for learning.
