Ur is the first town in the game, and has basic gear for sale that can outfit the first five extra Jobs. You won't find any Black Magic for sale here, though there is a copy of the Sleep Spell hidden in the Altar Cave if you're itching to use a Black Mage.
There is plenty of Treasure to find here, with the best items being hidden in a storeroom north of town. Follow the path north of the Weapons Shop, and be aware that there are random encounters similars to those outside the town in this grassy area. The Cure Spell in particular is a nice find at this point. You'll also find Items in various pots, as well as three Potions at the bottom of the well (which you can reach via a hidden path through the trees).
