Attached is a chunk from my .emacs with similar bindings as SLIME.
Turn on eldoc if you like it.

http://common-lisp.net/~trittweiler/talks/slime-talk-2008.pdf
might be useful.  The big comments preceded by ;;; 
in slime.el and swank.lisp should give you the basic idea.

Write a simple command that uses slime-eval-async and defslimefun,
e.g. ask for two numbers, add them on the Lisp side and insert the
result in the current buffer.

If you evaluate (break) you can see the backtrace which should give you
a live view on what's going on the Lisp side.  For best effect put
(setq swank:*communication-style* nil) in ~/.swank.lisp.  

Similarly on the Emacs side: insert (debug) in the source of some
interesting command and invoke it.  In the *slime-events* you can see a
log of the sent/received messages.
