The best way of finding answers for these questions, is to ask the embassy.

Usually their answer are formal and typical, that you might need to correct the names on your passport, try other certifications to prove the birthday of your wife, etc. You need to negotiate with them, and it always takes time.

My suggestion is you can try to find out what you can do now, if it is possible to correct the typos on your passport & marriage certificate, please do it. If it is really impossible, just tell the embassy what you have done and you've tried your best to prepare the documents. German guys are fair and reasonable, usually it won't be a problem that they deny the reunion visa and make you & your wife separate for ever due to some error if you're really married (no offence)

Yes, you can contact the Embassy's hotline and get your queries answered. They would give you the best possible answers.
