Warriors tend to have plenty of free skill points, especially if they rely on purchased or found spell books for any mage skills they may want to use.
I put 3 points into Identify (plus one from a quest and another from an item bonus) and 2 into Repair (found 3 items throughout the game with a Repair bonus, that I could equip to repair a bunch of stuff at a time to sell/trade for the highest value). If you are not going to repair loot before selling, then one level is enough.
Even without repairing stuff before I sold it, I picked up and sold all my loot and I reached the last part of the game with 1.3 MILLION gold pieces. Combined with the additional loot in the last part of the game, that was more than enough to outfit every single piece of gear I had (all of which had 5 charm slots, so 55 charms) with Gold Charms which cost 50,000 gold each.
