I will give you a quick rundown of what I have for the Fleet Air Arm, and you can add that to the Brits if you like.

*In response to the IJN Q, they were at war with China prior to Pearl Harbor, but I really think any date prior to 12-41 is academic at best for PAC.
*The AVG went into action for the 1st time in 12-41 "Flying Tigers".
As for the dates, I think some compromise is probably in order, for the most part, you want "deployed overseas" dates, or "first combat mission" dates, as long as they are somewhere "near reality". Like I say, you dont want the date of a USA based sqn in Seattle, you want to know when they had arrived in Theater ETO or PTO and were doing something, and you want to stay away from "the factory was making them" dates. I wouldnt sweat it too much, any dates are better than nothing. Do the best you can.
It should always be emphasised that anybody doing a setup should do a bit of legwork and check OOBs on their own anyways, the list is a handy quick guide, and exceptions should always be made for a good design.
