First thing's first: A Catch can't be worth the same amount of refresh as the power it affects, so that should be +1, not +2.
I find that a lot of invokes are spur of the moment, and driven by a situation. But off the top of my head,
Champion of Odin the All father could be invoked for social rolls, to give a bonus against someone who'd have reason to defer to Odin, or fear him. Or for knowledge of runes, or other things related.
I will smite the verily (aka itching for a fight): Troubles aren't really something you invoke much--they're, well, more trouble than anything. Though this I could say you might invoke for a bonus when trying to provoke someone.
Norseman by blood and virtue: Knowledge of the Norse (declarations), fighting ability, drinking ability...
My faith tested my faith restored: Invoke for bonuses to Conviction or Discipline when someone gives him reason to doubt (this one's kind of narrow, though)
I am worthy of Thrudstok (The mace/scepter of Odin): I'd say for any rolls relating to the use of the mace.
