I went with the ice,fire,regular hammer skills for the most part and the sword master skill. I noticed the aerial AOE skill is pretty powerful though, so you might want to put a few points into that too.
It's actually a lot more complicated than you think. You really don't have enough skill points to learn all those skills because you need to save points for the later jobs since they do carry on. In open beta, i'm not sure if you get another one of those reset scrolls. Not to mention, your build will change depending on if you are PvE or PvP oriented.
On your first job as warrior, you actually ditch most of your skills. As a Knight, you don't have enough points for Sword Mastery or any of the Hammers if you want to capitalize on your 2nd job offensive skills.
