Two ounces should cover it, but sometimes you'll get a tester that wants a little more. I would take 3 just to be safe.

Also, hand warmers are a great way to keep it warm and IMHO... I would stay away from the condoms. There is a possibility that they could burst leaving you screwed. Travel shampoo bottles work great for substitution. Just remember to get your sample right before you go take the test. Human urine starts to break down after 8 hours, unless its frozen.
