It is the 1.8T and I have no doubt that the sludge is clogging things up.
When you look into the engine instead of seeing machined parts you see an
amorphous composition that hardly resembles anything mechanical.

Yes, when I did it myself I got it from Audi and the previous filter was
also the long one. Not sure about the heat shield, but there is a lot of it
on the engine and some kind of foil wrapped around one of the tubes on the
passenger side and some folded foil/insulation around another tube.

According to the records the problem first began at 25K before the warranty
extension letter from Audi came out and the dealer was still using dino oil
and the short filter. I've only owned the car for about 3k miles.

Not yet, but I've driven it less than 100 miles since then, and both
episodes happened after 5 hours of driving with only one or two brief stops.
Hell, I just looked in the manual and saw that the oil level indicator light
has the word MIN printed with the oil can icon. The indicator light I had
was for oil PRESSURE just as I thought and as the symptoms indicated. I'm
thinking of installing one of those after-market dial pressure gauges so
that I can get a better idea of how bad the problem is, but I don't want it
to look jury-rigged.
Anyone have any advice on how to be a squeaky wheel and actually get some
beneficial service done to it?

If what you see is a foamy tan looking goo you might have a problem with the
head gasket leaking coolant into the oil. If so that it a big issue that needs
to be corrected by pulling the head and replacing the gasket.
There are conditions where condensation from short drives combined with cooler
ambient temperatures can cause this goo and the only thing it needs is to just
drive a longer trip allowing the system to warm for a longer period of time to
evaporate the moisture.

I would recommend that you attempt to duplicate the conditions under which
the oil light previously appeared and see if it comes back on. The problem
is if you don't get the oil light to come back on, you won't have much of a
case to argue. Your oil pressure switch is on the oil filter bracket and
from what I can see in the manual, you remove the switch and then install
the appropriate fitting with tubing to your oil pressure gauge. With engine
warmed up, Bentley manual says you should get more than 14.5 psi at idle and
more than 72.5 psi at 3000 RPM. Haynes says at least 29 psi at 2000 RPM. It
is also possible that the recent oil changes have removed some of the gunk.
If the light doesn't come back on and your oil pressure measures OK, then I
would use one of the recommended synthetics http://tinyurl.com/82xga in a
5W-40 formulation (not xW30) and do several oil changes over the next 10,000
miles.
IMHO this would not be a car I'd be looking at keeping for the long term.
Because Audi stupidly increased the oil change interval and allowed
continued use of dino-oil, there was no longer any safety factor to protect
the owner who went slightly over the maintenance interval. Because of that,
your engine has been essentially abused in its early life and the resulting
excessive wear on internal engine components has probably shortened their
lives considerably.
