So theres this program called MC edit for minecraft that is really helpful. Its pretty much a mod that you can spawn stuff, delete large groups of things etc.
WorldEdit is much better, it allows you to do the same things but in-game.
It is mainly used for servers but if you download the single player commands mod it comes included.
