Question II: Does your Spell Penetration count when you use "on-hit" attacks? In short, does a spellfocus improve your chances with Tartarian Chains?

No. Penetration doesn't affect spell-like effects from on-hit items. They are totally seperate weapons and have no impact from penetration.

I know for a fact that having a big pile of Fire Magic improves the fire damage inflicted by your charcoal shields...

Fire Magic affects the Fire Shield Spell (7+1 Damage per level of Fire). And the Charcoal Shield just gives you a Fire Shield and any current levels of Fire are added to the effect by Hardcode. I can't think of any other items that are like this off the top of my head, even Regeneration and Nature Paths.
