In addition, back ground states the Narada was build with a mix of salvaged Borg crafts by the 24th century Romulans. So imagine the advancements the Klingon have made after 25 years of reverse engineering, and not just scans.
You can argue the above is canon or not, but it is what the screen writers stated and will be available on the DVD deleted sceens. I'm inclined to believe Spock Prime will share, as who knows what the Klingons learned from the Narada after 25 years.
IMO, the question of if Spock should or would share information is closed. He will or the weakened Federation does not have a chance.
It's still a non-issue because the Klingons learned as much as the Feds did with their scans. It's not like they ever set foot on the Narada or gleaned any more info from it than the Feds did. Plus they lost 47 ships where the Feds only lost 7 I think it was? And unless the Fed fleet that was elsewhere is larger than 40 some ships then the Feds were already behind as it was.
The Feds are really no worse of with the loss of the Vulcan planet than the Klingons are. It's not like the Vulcans were a heavy military force to be dealt with.
