Don't think there is a better enchant than crusader.
In terms of talents you should get Earth's Grasp and Glyph of Stoneclaw Totem as your first Glyph because the shield is incredibly strong on low level.
You need imp ghost wolf since you spent most of your time walking around while leveling.
You should get shamanistic focus, it's a big mana saver.
Ancestral knowledge isn't worth it. You should put your last talent points into imp shields because lightning shield does a lot of dmg.
I'd use this build for leveling:
