1. choose your lisp dialect: do you want to learn CL, Scheme, Arc, ...?
2. randomly pick an implementation of your chosen lisp. It really makes no difference as a beginner. I speak from experience. You can always switch later in a painless way.
regarding CL, choose an open source implementation if you don't fear things like emacs. If you prefer a more polished IDE, choose a commercial implementation.
