I think, the easiest way to take care of griefers and teamkillers is the rank system. The more points you have, the higher rank you take, and the higher rank you have, the more thing you can do.
But first of all, the intel carrier killers should take bonus points, for example 5 points for 1 kill.
With 0 point everybody could use only the rifle. Nobody could build or destroy anything. So the first part of the game would be only fighting while using the terrain advantages.
With 5 points (5 kills / 1 intel carrier kill / 1 intel capture) the players could be builders and could build, mine, and destroy, but only their own buildings or the buildings of their enemies.
With 15 points the player could be grenadier, could use the grenades and could destroy the buildings of his teammates too.
With 35 points the player should become sergeant with the right to kick any of his teammates below his rank.
With these ranks, the griefers couldn't destroy anything on the map from the beginning, and they couldn't grenadespamming. But if they reach 15 points only to start griefing, the sergeant can kick him immediately.

And one more thing, the teamkillers. It's easy. If anybody kills his teammate, he automatically changes side and loses all of his points. At this point, he will find himself in the middle of the territory of his ex-teammates, who have the right to shoot him down for an easy frag.
