Ah. Glad to see I least got the need for reftex-format-ref-function 
correct.... I figured that since it returns a string, I might be able to 
use it in place of one -- obviously not!

I had to change that last line to:

(setq reftex-format-ref-function 'my-reftex-format-ref-function)))

but beyond that it works brilliantly (and I've learned a couple of 
important things about Elisp and AUCTeX in the process). I've put the 
code into my own refstyle.el and it loads and runs perfectly. Thanks for 
the help!
