Here's a thought: what would it take to set up something to record the oil
pressure and temp, either as a curve or a series of readings, on a palm or a
notebook? Just a thought. I've often wondered about oil pressure during some
of those corners, particularly a "carosel" kind of thing...

There is no reason to put gauges on the a-pillar besides having them in
plain view. Pressure and temp gauges really don't need constant
monitoring and I think you'd be less frustrated with the gauges in the
future if you put them elsewhere on the dash. On the a-pillar they'll
just be blocking your view, and if you're trying to look at them during
a run, well, you're not going to do very well! :-D
If you're worried about oil starvation under high loads (a genuine
concern with a stock engine and autox tires), you can get one of the
expensive Greddy or HK$ gauges with an alarm integrated in it.

Modern RX-7 dash temp gauges are like this (fortunately I've got an
older RX-7 :), the needle goes to the center two minutes after the
engine's running and stays there until it starts to melt. There's a way
to defeat this but I do not know it off the top of my head, but at least
you know there's something to search for.

If you're worried about oil starvation a pressure gauge will tell you,
but you'll need a copilot to tell you about it. Water and/or oil temp
will tell you if you're abusing the engine and its cooling capacity by
spending a minute or so at full throttle. And they'll tell you after the
run when you can pay attention to them.
