There is some good advise above.
I STRONGLY advise against going to a hotel room and napping on arrival even though you may be quite tired. I've made that mistake and it prevents adjusting to the new time zone.
The best approach is to park your bags and go for some serious walks in the sunlight.
Try to stay awake until 9PM Paris time.
Have snack supplies in your room for the famous 1:30AM awakening the first night. (dinner time in the USA)
Paris is a fabulous place!
