Crazy thing happened, now car won't start

Ok for the ignition coil I'm getting 0.4 ohms primary, and open circuit secondary (negative on top pole) so I'm assuming that's a bad coil. For the CPS/distributor stuff I'm getting (in order of G1, G2, NE) values 228, 222, Open circuit -- with negative on G. I checked 4 times, with several hours between the first two and second two checks, and got the exact same results.

So I'm thinking this happened:
1) Ignition Coil failed/spiked, sending large amounts of current down the wire, burning itself out in the process
2) Spark hits distributor, burning out the first thing it sees (NE sensor)
3) ECU looses ability to determine RPM and promptly stops trying to send sparks (not that sparks would hit anyway)
4) When key-on-engine-off with diagnostics mode jumpered, the ECU notices "No signal to G1, G2, or >>NE<<".

So, does it sound like I figured it out?

Here's what I'm planning on buying on friday, unless you have anything to add:

(I already have a set of brand new spark plugs)
