X2 on the overpack, don't take more than your outfitter tells you.
A couple of things though.
Do take rain gear. Even if you don't expect to use it, it don't take up much space and is good insurance to keep the rain away, or wear in the early morning if you are going when it is still cool in the mornings.
Take a boonie hat. Rolls up and takes little space.
Forget the 3D cammo, unless you know that there are broadleaf trees in the area. Don't make sense to have leafy cammo in Thorn country.
I wouldn't take shorts unless you like bleeding legs.
Wear one pair of tennis shoes on the plane and for around camp and take two well broken in pair of hunting boots.
Remember to leave plenty of space in your baggage on the way over so you will have room on the way home for all the souvineers you buy over there.
Buy a blow up neck pillow for the flight over. Use your back pack for your carry-on and the pillow can go here, along with a book to read on the flight, camera, etc.
Gum, hard candies, etc. go far with the trackers and other locals that you run into.
