didn't see it mentioned, but even though your in the middle of a rain forest- dehydration is a very real concern- a small hydration pack would probably be pretty handy, for treatment I know that much of the water in Peru has a lot of sediment that can quickly overwhelm a filter- if your going the filter route, consider a pre-filter (bandana would do)
also mentioned above, but probably bears repeating- getting a fire going (and staying!) can be rather challenging- easy lighting, long burning tinder is essential (PJCB's, Wetfire, ranger bands once lit are habdy for getting a fire going in the wet)
I'm going to do this trip someday in the not too distant future so please be sure to take a lot of pics
