Coffee gets added twice, 2 oz at flameout and 2 oz around bottling. However, I re-read the original recipe from BYO and they state to add the second 2 oz in the secondary. I don't secondary, so I added at bottling. I think you want to avoid boiling the coffee, but you could add the coffee to the priming sugar/water, or make the coffee, and dissolve the priming sugar in that.
