For #1 I would clean all the connections on the throttle body with a
spray contact cleaner. WD40 will work in a pinch. You could just be
describing a dirty connection on the TPS which is fairly common on the
older beasts.

I've been trying to get mine to play nice on cold start for 4 years
now - and I've about given up. I'm pretty sure it's a problem with
temperature and the computer somewhere. My throttle body and
everything associated with it were one big heap of gunk when I got it
and a really thorough cleaning got rid of the majority of the problems
and changing the O2 sensor got rid of a lot more, but those all had
sympthoms beyond just dying at the stop sign. For the first 2-3
minutes it still does that BUT only when the outside temperature is in
the 50 degree range. Cleaning the throttle position sensor leads helps
a little but the idle still drops way low at the stop sign at the
bottom of the hill - sometimes it catches and is fine, sometimes it
dies. If it's good and cold or nice and warm out, no problem - just
that one temperature range that usually comes in the Spring and Fall.
Aside from that, no problems so I've pretty much decided to leave it
alone and expect it on those chilly but not cold mornings.
