My best shot at boiling all this into one sentence: Does the added complexity a two-Apache configuration offer performance improvements/overhead-reduction that make the complexity worthwhile?

It depends :-)

Did you read what the mod_perl guide has to say on this issue? If not, do it now: Choosing the Right Strategy is a very complete and helpful document.

Besides that, it really depends on your traffic. I never cared to set up a reverse-proxy (because my servers work fine without it), but if I ever get the feeling that the servers got slow, I'd implement it.

For some advanced setup issues, perrins articel Building a Large-Scale E-commerce site with Apache and mod_perl is a good read, too.
