You're welcome... :)

Good luck! I'm sure you'll have fun with CL.

Something like
(defun add-artist ()
(with-output-to-string (*default-template-output*)
(fill-and-print-template template/printer values)))
should do it. Note that FILL-AND-PRINT-TEMPLATE prints its output to
the stream *DEFAULT-TEMPLATE-OUTPUT* and TBNL wants a string returned
by the handler, so the code above makes sure everything printed to
this stream ends up in a string which is returned by the function.
This assumes that ADD-ARTIST is a handler, not a dispatcher.

WITH-HTML is the macro which uses CL-WHO from the test suite, right?
If that's the case you must wrap the form (GET-PARAMETERS) with
something that asks CL-WHO to include it in the output, otherwise
it'll only be evaluated for its side effects. One of
(str (get-parameters))
(esc (get-parameters))
(fmt "~S" (get-parameters))
should do it.
Does that help?
Cheers,
Edi.
