Coils are still on order, but did a little poking around under the hood over the weekend. I cleaned the K&N drop in air filter, and noticed while I had the airbox out that the throttlebody had quite a bit of buildup around the plate, which I cleaned up with some carb cleaner on a cotton towel. So far, the car starts easier again, and the idle has been a lot more steady.
When I swap out the coils, I'll take the TB completely off, and clean up the rest of the buildup I couldn't get to with it on the car.
