I will only comment on the commuting part of your post, having been a commuter from Japan to the US for the last 7 years I can tell you that it depends on your commuting conditions, positive space business class round trip ticket every month then it is no problem (except for the jet lag issues, no way around it) anything less than that, ZED or space available, coach, the company always sending you on a different airline, different port of entry looking for the cheapest ticket....etc, then your commute will become the main reason of your discontent.....!

Good luck
