SO the last test was that I put the suspect coil on cylinder 9, zip tied the connector on 8 to a known good coil pack, put the suspect rubber boot on cylinder 2.
I got a new misfire on 9 and the other cylinders (2 and 8) weren't giving me any codes.

So I bought a new coil and replaced the bad one on cylinder 9, and was surprised to get a code P0359 but quickly realized I forgot to attach the connector to Coil 9 in my excitement.

Now it runs great! Thanks to everyone for their help!

I think I will try that other bottle of seafoam now!
