How do I come up with a argumentative thesis statement that incorporates three literary elements in Big Black Good Man?

You are on the right track.  'Literary' elements include
about everything you can think of in a written piece:

the
theme of the story (like 'revenge' in Hamlet, for
instance);

the story line or plot (what happens to whom and
why);

the setting (and this includes both the physical
setting and the time or period in which the story takes place– along with the customs
appertaining);

the characters (both their created
personalities and the way in which the author portrays
them);

the author's viewpoint on any of
these;

the literary techniques and devices that the author
uses to create his piece and express his viewpoint;

and the
overall impression that the finished work makes on the reader– its genre, its message,
its art.  This last to me is also a literary element... or at least the cumulative
effect of all of them!

Generally, a good thesis and its
statement will incorporate at least two and probably 3 of these aspects:  "A interacts
with B to create C for the reader" is one common template for utilizing three literary
elements.
