You can't pick up monster spawners in Minecraft. You can use a mod like too many items to give yourself monster spawners. To break them, the quickest way is a pickaxe
Monster spawners do not (as of the version 1.3.1) ever contain creepers naturally. It is possible to get a spawner that spawns creepers by editing the game's code or by using mods.
Mossy cobblestone can be found in dungeons with monster spawners far below the ground level. They can only be found naturally and can not be crafted, and can also not be used to craft anything else. However, Notch, the developer of Minecraft, has said that mossy cobblestones will be used for crafting in future updates.
No, there are no creeper spawners naturally. Additionally, monster spawners will not spawn endermen or passive mobs (i.e. pigs, chickens, cows, etc.). You can although, download something such as not enough items, to obtain one.
You can find iron ingots in chests next to monster spawners. But because monster spawners are rare then it would be a lot easier just to mine until you find some iron the melt it in a furnace! :)

More mobs, craftable spawners, and zeppelin.

No, the monster spawners are not available as a placeable block, even on Creative.
