If you're adding more than one or two branch ducts, be sure to do a Manual
D, because you'll probably need to increase the size of your supply and
return trunk ducts.

That is why I will be hiring (and probably paying dearly for) expert
assistance. The bids I get will specify that I want a whole-house study, not
just a light-bulb switchout. I know just enough to be dangerous, and this
will probably be a 4-5 K job minimum, so I won't cry over a few hundred for
the guy to do a site survey.

Yes, I agree. This job includes the heating cooling load study and I'll
be paying close to $6000 for the entire job. I'm not crying over a few
hundred dollars, that is not the issue. My concern is that everyone
should do what they will be hired to do. Problem on the newsgroups is
that as soon as someone mentions a problem, everyone thinks the guy is a
DIY trying to go the cheapest route. This is not the case. I just want
to make sure I'll be getting what I pay for.
