Possibly Nero tried to use Robau's shuttle from the Kelvin on some sort of reconnaisance mission when he was captured leaving his crew to find him. It is unlikely the Klingons had any real sense of the Naranda's power and technology before their ships started falling like clay pigeons.
Unfortunately, I didn't read Countdown (still plan to), but think about this: What better a bargaining chip, than to make nice with the Klingons by sharing more advanced technology promised to give their cherished empire a major advantage over the Federation? Hence, you have a major problem the Federation would need to "nip in the bud". Don't forget, in the movie Nero mentioned a desire to see Romulus being free of Federation influence. That being the case, why wouldn't have have somehow managed to communicate these advances to them
for the same purpose--to give them a technological advantage? In any case, I think the next movie should definitely include Spock Prime's having shared his knowledge so as to ward off trouble from some not-so-neighborly adversaries.
