Some of this has probably been said by others above, but here are my observations:

1. Only see I pair of biking shorts. Might consider taking two.
2. 0-1 pair(s) of underwear is good.
3. Don't need 3 pars or shorts. I take 1.
4. REI microfiber towels don't cost much, dry fast and save a lot of space. Ditto a washcloth... look for one that advertises that it "never needs washing." I have this one: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 and am very happy with it.
5. Too much tape. Roll some on a pencil or your pump. Easy to get on the road if needed.
6. Instead of towel in tool kit, cut up a couple of pieces of cloth for cleaning/lubing chain. Add several disposable wipes for cleanup. Bring blue disposable gloves (I like the think ones from Harbor Freight that can be used over and over).
7. Ditch the bulky, heavy tarp in favor of a piece of Tyvek.

All of the items above are either free or cheap. You could also replace both sweatshirts with one polyester thermal top for riding, although this would cost money.
Additionally, you can't take the fuel on the plane. Some research is in order regarding purchasing fuel in France.

EDIT: Here if Tyvek by the foot:
