Level all class skills, bow, dual wield and 2 handed as equally as possible. You want to get whirlwind, dragons blood and the Passives battle roar and mountains blessing as quickly as possible. On my Stam dk I alternated weapons and always had 3 class skills and 3 weapon skills in my bar even a weapon skill I couldn't use just to level it. Something like this:
Dual wield: flurry, steel tornado, uppercut, unstable flame, obsidian shield, magma armor
Bow: scorched earth, poison injection, molten weapons,burning breath, reverse slash, take flight

Both uppercut and reverse slash are two handed skills that you can't use without that weapon equipped but you can still level the skill line of they're on your bar. You'll want to wear medium armor and put attributes between stamina and health
