Heart of the Anvil and Heart of the Golem (spoilers)

[Greywolf]

So I got up to the quest Unbreakable Metal and at the end I have the option to give both the heart of the Anvil and the Heart of the Golem to the paladin of Torg but nothing seems to come of it? Should I hold onto these items or are they supposed to be given here?

If you give both Hearts to the dwarves they will use those to craft Harrim a unique helmet. The crafting will take some time, and they will deliver the finished item to your throne room later just like your artisans.
Edit. If you want to check the stats on the helmet, here's a link:
