Basically I have a horizontally split 'screen' session, code in the top and repl in the bottom, and I just ctrl+[c+c] to send paragraphs from the top to the bottom. I don't remember if vim-slime comes with it or if I augmented it, but I also do ctrl+[c+f] to send the current Lisp/Clojure form, ctrl+[c+l] to send the current line... Or just ctrl+a+tab to switch screen windows and type in the REPL directly.
