I'm looking for general guidance on preparing for emergencies for international travel.

1. I've been told to always keep with me the telephone # of the U.S embassy and state department.
2. I've been told to keep photocopies of my drivers license and passport. Other than my wallet, what other locations should I keep a copy?
3. Its probably best to take a 2nd ATM and 2nd credit card as a backup, but where should I store my backup cards?
4. In case of theft, is it a good idea to keep some spare cash in my shoe or are those money belts a better option?
5. Keep a record of international telephone numbers of my credit cards in case I have to report them lost or stolen.
6. make sure I'm covered under my medical insurance when I'm overseas
7 Ask my Dr. for an antibiotic prescription before leaving in case I get sick

Is there anything else I should prepare?
