Skip CL for now, and use Clojure or Racket. CL's ecosystem requires some hacking to make it work pretty often, and the only true editor for it is Emacs and Slime, so it's not a great out of the box experience.
Racket comes with an editor and a ton of libraries, so I'd recommend checking that out first (and then coming back to CL later maybe)
