boreas,
Don't worry about shots/pills - no requirements for air travel. Do you have room for your fins? Where are you staying? There is probably no need for blanket/sleeping bag. I would buy insect spray where you live (the kind with high % of Deet & read the warnings) then store it in a small ziplock baggie. Don't forget a hat/cap, sandals & small flashlight. Toothbrush & paste (Well, it wasn't on your list!) Did you decide on CC or AC? Wherever you go, have a blast!
Please write a trip report for us when you return.
