I wiped everything up and cleaned the plug wires the best I could and tried to start it again. no deal. it appears there is oil leaking down into the tubes from the valve cover/head interface. Guess I'll go ahead and change the valve cover gasket. The plugs appear to be new as viewed from the top side. I haven't removed one yet though.
get new ones while your doing the valve cover gasket.
might consider new wires too..
but this still might not be the answer to the no start.. but is most likely the answer to the crappy running.
Here's what I found when I lifted the valve cover. Changing the plugs and gasket tonight. The plug wires appear to be in almost brand new condition so I'm going to try some electrical parts cleaner/degreaser on them first. If that doesn't work I'll replace them. I really appreciate everyone's feedback. All four of the plug cylinders were in nearly the same condition as shown in the pics. No evidence of any cracking in the valve cover after a cursory inspection. Gonna run it through the parts cleaner this evening and inspect it more carefully.

Simple question but hows your battery life?
Battery was replaced on Wednesday.
just watch what kind of solution you have in the parts washer.. the "good stuff" is for metal parts only and will distort, eat away at plastic parts like the valve cover..
Anyone know what the torque spec is for the valve cover bolts? No Chiltons or Haynes manual available for this car? What's up with that?

SHE'S ALIVE!!!! After replacing the valve cover gasket, plugs, and plug wires she still wouldn't start. Turns out those components were all in bad shape and I'm glad they've been replaced but it turns out that petrified.rabbit was correct, it wasn't the cause of the no start. I ended up pulling the oil pressure sensor as suggested, cleaning the sensor and connector ends off, and reinstalling it. Had to jump start it but she fired right up! I'm a little puzzled as to why this caused the no start though. Anyway, thanks to everyone for your input and hopefully this info will help the next guy having this problem. Thanks again everyone!
Pic shows the plugs in the condition in which they were removed.

the sensor cuts either spark or fuel to prevent damage if you run it out of oil.. so if the sensor thinks you have no oil (or not enough) in it, it will kill the engine..
