The world generated using the code -8227252585264349741 is pretty great, and it works for minecraft 1.2.5. You start by spawning right next to an npc village, and only a dozen blocks away is a surface dungeon. The coordinates for the village are X: -122 Z: 231, but you should just see it when you spawn.
If you explore in the cave system beneath the first dungeon you will find a double dungeon with only one mob spawner but 3 chests.
The coordinates for the double dungeon are X: -72 Z: 230
Under the village is a large ravine with a ton of exposed minerals, the coordinates for the ravine are X: -142 Y: 24 Z: 266
