Why wait? snatch it out the postmans hands and rip into it and test there and then!
the control solution is just to check the meter is (still) reading correctly, as it's brand new you shouldn't need it. if in a year or 2 the readings seem off you can always order some.
Have the meter by your bed and test first thing in the morning, that will give you your fasting test, test before a meal and then 2hrs after, you don't have to test for every meal, one day do breakfast, the next just lunch and the day after just evening meal. You'll work out what foods/portion sizes are good or not for your BS level.
