Thanks for pointing this out, I have a feeling the find-func
functionality will quickly become core to my elisp file navigation.

To answer the original question, I also tend towards a minimal setup.  I
do all of my editing directly in elisp source files, and I don't use
tags or etags or anything like that.

I use the describe-function and describe-variable help functions with
tab completion *very* frequently to find functions and variables
relevant to my current task, and to then jump to their source.

When drilling into either a bug or unfamiliar functionality I find
edebug invaluable.  Evaluating functions with a prefix argument "C-u
eval-defun" instruments them for interactive step-by-step evaluation
with edebug.

Also, I highly recommend both paredit and the sexp-edit operations
(kill-sexp, paredit-backward-up, paredit-forward, etc...) to anyone
working on any lisp source code.
