There will always be a blacksmith but he will not normally hang around the blacksmith house. Look around for a villager with a black apron, that is a blacksmith.
you can get it from npc villages. here is a seed for a npc village: FINAL
You can't.
An NPC village really has no useful purpose. It is mainly for looks and so you can interact in fun ways with the NPCs, such as using them to trigger and/or test traps.
Every map has them, as they are randomly generated.
Just look around. They randomly generate, so there is no definite location.
No.
No.
Because the current version of Minecraft on the Xbox 360 is not as up-to-date as the PC, the trading feature with an NPC villager does not exist. When Minecraft updates to that specific version, NPC villagers will be able to be traded with.
You don't make it. You find an npc (non-player character) village and give the priest a diamond and he will give you a bottle o chanting.
Yes, if you have the recent update of minecraft 1.2 it will work.
NPC villages are currently not in the code for generated structures in Minecraft: Pocket Editon. Therefore they cannot be generated in any seeds in the game, and are only able to be generated in worlds on the PC version.
There are many ways this can be done. One way could be to find a NPC village and hope there is a blacksmith shop. Then, if there is a blacksmith shop, try to find iron ingots in the chest. Also, you could go through caves and on extreme luck, not have to mine at all and happen to find the stronghold and get a chests with iron ingots. In the end, just make a stone pick and mine iron. It's way easier.
