I think you're approaching this the wrong way.  Lisp is full of
utilities for trees, e.g. PRINT, READ, EQUAL, SUBST.
I think a pretty printer is much more useful than a package for
drawing pictures of trees.  One other thing that you may find 
very useful is a "structure editor".  This is not part of CL 
but has been implemented many times and I'm sure is readily
available.  If you have trouble finding one, let me know.
