As to what driftwood to use, it's pretty much depending on what's available in the local area. If I said you should use X from Africa or South America, then it's highly likely that you'd be hunting that type down for a year without finding it, whilst Y is readily available in Singapore, because it's a Thai wood and equally good.
If you can, find a few different types of wood and mix it up a bit, then you have less worry about the potential of choosing the "wrong" wood. It can also be made to look BETTER with a few different types of wood, because it gives some variety.
Unless you've got plenty of experience in picking "wild" wood, I'd go to the fish shop and choose something. That way, you know (well, sort of at least) that it's not bad for your fish.
Any driftwood should be cleaned and soaked for 24 hours (at least) before it's put in your tank. Some people recommend boiling it too. If it's material that isn't from the local fish shop I'd definitely make sure it's boiled before it's put in the tank.
