Hi and welcome to the forum

,
1st:
Ores and Gems you need for "enchanting" of weapons, armor and jewellery.
But if you haven't enough money, you can sell a little bit, but I only sell some of the Iron. Iron is only needed for the two lowest enchantment-levels. There are 10 levels and for each kind of enchantment you must find a "Formula"... and you must find a guy named "Dreaven" who can enchant or disenchant items.
And if you wish: finding an item with an enchantment you wish to have for your favorite weapon (if it has 1 or more enchantment-slot(s)!), you can disenchant that item to collect immediately the formula of that enchantment and you can use that enchantment right away by Dreaven IF you have the required Ores and/or Gems with you.
2st:
I don't know what difficulty you play (low, medium, high?), but invest fast in Lock Pick .... I don't do that now I play on "high" ....

Stats:
if you play like a warrior, good to invest in Strength & Intelligence too. Strength (and Dexerity for bows) is required for most of the weapons, especially melee weapons.
Also can Strength, Dexterity and Intelligence increases your Resistances and your Reflexes, etc ...
I haven't play like a pure warrior get ... so I can't say more than this for help with your character.
Success !
