If you want to go fully literate you should give org-babel-clojure a look. org-bable is a literate programming extension to the emacs org-mode.
If you want to use nrepl the following should be added to your .emacs:
(defun org-babel-execute:clojure (body params)
"Execute a block of Clojure code with Babel."
(let ((result-plist (nrepl-send-string-sync (org-babel-expand-body:clojure body params) nrepl-buffer-ns))
(result-type (cdr (assoc :result-type params))))
(org-babel-script-escape
(cond ((eq result-type 'value) (plist-get result-plist :value))
((eq result-type 'output) (plist-get result-plist :value))
(t (message "Unknown :results type!"))))))
