this is a Superflat world I put together  and it has all the stuff you need to do survival except for villages though. it has trees, sand, stone, all the ores, and obsidian. Even pumpkins. It has mineshafts and possibly Strongholds for you to get to the enderdragon. Yes all these great things and it is all flat to give you easy building abilities.
     (updated): no with water and lava at the spawn point
