To continue the echos, the contents of the PADI wreck specialty really does depend on the instructor. If your instructor does tha bare minimum you'll come away with little more than an expensive cert card and the knowledge that you shouldn't touch unexploded munitions should you find any.
The advanced nitrox route mentioned above is the way to go if you're really serious.
However you go about learning to penetrate wrecks just make sure that the person who is teaching you has experience and knows what they're talking about. I've seen far too many people who think they can run off and penetrate wrecks left right and center without proper training because they have their PADI wreck diver card.
