My opinion
The problem is very unlikely to be the spark plugs, especially given that they were replaced relatively recently. I believe the service interval on 2001 plugs is 60k miles. And even then they degrade gracefully and don't start misfiring at 60k miles. I think thait's just a waste of money. to replace them. If you're really concerned you can pull one of the plugs that is throwing a code and inspect it. My guess is that it will look just fine.
Swapping the coils is a good diagnostic step but is probably not necessary. Almost always, coils that fail even when it's not raining have obvious visual flaws, such as cracks.
The other possibility is that the plugs on those two coils aren't seated properly. If that's the problem, swapping them may make the problem go away and lead you to the wrong conclusion. :)
