Let’s dive into those questions of yours.
Camera: You’re about to enter one of the most beautiful parts of the world. The mighty Andes and the lush Amazon provide amazing opportunities for photo taking. So we recommend bringing a camera if you are able. However, if you choose not to bring a camera don’t worry we make sure to share group photos in a google drive at the end of the trip.
iPod: As long as it doesn’t have wifi capabilities you’re more than welcome to bring it.
Money Belt: Whenever you travel, including in Bolivia and Peru, its smart to have a money belt and also to split your money up into different places on your body and in your bags. You can usually find money belts in outdoor stores like REI, Eastern Mountain Sports or (the best option) support your local gear shop. Often those big department stores like Target have them as well.
