{Thalia, Guardian of Thraben}
Will it affect flashback or Unearth spells eg. {Unburial Rites}?
By using the flashback ability
Yes it does. A non creature card being cast for its flashback cost is still being cast. It is simply an alternate casting cost cost. I will find a ruling when I get home, if someone doesn't beat me to it.
601.2e (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=601.2e): The player determines the total cost of the spell. Usually this is just the mana cost. Some spells have additional or alternative costs. Some effects may increase or reduce the cost to pay, or may provide other alternative costs. Costs may include paying mana, tapping permanents, sacrificing permanents, discarding cards, and so on. The total cost is the mana cost or alternative cost (as determined in rule 601.2b), plus all additional costs and cost increases, and minus all cost reductions. If the mana component of the total cost is reduced to nothing by cost reduction effects, it is considered to be {0}. It can't be reduced to less than {0}. Once the total cost is determined, any effects that directly affect the total cost are applied. Then the resulting total cost becomes "locked in." If effects would change the total cost after this time, they have no effect.
Thanks

Unearth spells
Assuming you mean creatures with Unearth as an ability like {Fate Stitcher}, no. Unearth is actually just an activated ability, not a casting cost. Since you're not casting anything (let alone a non-creature spell), Thalia doesn't affect it.

Oops I completely ignored the unearth part of the question. Thanks for picking up on that! I was responding to the cards that were linked lol.
