Question 2002 Nissan Sentra 1.8L ECM replacement

I need to replace the ECM on my 2002 Nissan Sentra 1.8L. I've already gone over the 80k miles that would have allowed me to replace it due to the recall. Anyway, I need to know how to find the right ECM. Do I need to pull the old one out to get it's part number or can I just order it based on the year and model of my vehicle? Second question, will it need to be flashed or programmed once I install it? If so are only Nissan dealerships able to do that?
