Good suggestions already...remember that you can probably buy t-shirts there too so you can save a little space there.

Some cards might be useful for killing time on the train with other westerners playing poker...depends on how long your train/bus trips will be.

Travel sized hand sanitizer...Toilet paper (in ziplock bags) in case you get caught in a downpour...small phrasebook...or better yet write out the phases you think you will need in a smaller book and bring it with you. Small light rain poncho that covers your backpack. Extra socks.

a backpack lock is possibly worth it...it depends on how far you will be from you bag.
