Sounds like you have it covered! I did this to mine just two weeks ago now, pretty straight forward.
You'll need to short the neutral start switch (near where the reverse lights plugin, in the engine bay) which is as simple as pluging the two connectors into each other. And you'll also need to cut the shifter hole to go further forward (toward the firewall) as that's where it comes through.
Oh, you'll also need a spigot bearing as the auto doesn't have one
