Hey Fox, good progress and I think you will enjoy the EFI. Turn the key and go.
You will likely have to get the computer flashed to set it for the new configuration once you get it all up and running. I have heard good things about CCMR shop here in the Grove. You could probably start with a conversation with them to get an idea of what will be needed.

Keep on posting,
Steve
