I think it has something to do with their naval power, which is why I wish CK2 had naval battles & that independence wars was based on keeping your own holding instead of sacking the enemies capital etc.
Most likely not, the Skagosi haven't had a fleet since they were conquered by Brandon IX Stark, he destroyed their fleet and forbade them from the sea, they weren't allowed to build more ships for the exact reason they might rebel, my guess is they were preparing for years, they had been training warriors, growing the population, building weapons and armor and finally decided it was the time to strike, but after a bloody war they failed, but managed to take down the head of house Stark, an achievement in itself.
All that said, as part of the war they could have built ships but my guess they would have had to do it quickly and after rebelling otherwise the Starks would have found out and put a stop to it, so if they built a fleet it wouldn't have been big, but again, that said, the North hasn't maintained a powerful fleet since Brandon the Burner, so a small Skagosi fleet may have been met with a small Northern fleet, but that doesn't account for the thousands dead.
EDIT: On your independence war problem, that is already how it is, if the 'rebels' keep their holding they get a large buff that grows over time.
