Just to follow up on this post;
I figured out how to do what it is that I needed to do using fields that I created via lisp. What really ate my lunch was the ObjectID in a 64 bit system. Lee Mac wrote this, though, that cleared it all up for me:
(defun GetObjectID (obj)
(setq util (cond (util) ((vla-get-Utility
(vla-get-ActiveDocument (vlax-get-acad-object))))))
(if (vl-string-search "X64" (strcase (getvar 'PLATFORM)))
(vlax-invoke-method util 'GetObjectIdString obj :vlax-false)
(itoa (vla-get-Objectid obj))))
