DrRacket got me up and running in Scheme with little to no thought. I didn't really need to learn anything new in terms of the tools needed to work the language. Furthermore, you get access to tons of packages for the PLT/Racket environment. I installed Vi mode (http://planet.racket-lang.org/display.ss?package=vi.plt&owner=kazzmir) for DrRacket which made solving the SICP exercises a little less painless.
Here's a guide that spells out setting up DrRacket for SICP. It's really easy.
