There are a lot more places worth the visit in Bolivia, apart from the Yungas and Potosí. Salar de Uyuni, Sucre (especially the Indigenous Art and Textiles Museum), National Reserve Torotoro, Pantanal (the Bolivian part is better than the Brasilian part), Tarija, and a lot more.
Bolivia is at least as safe as the USofA. Just stay out of Chapare and keep an eye on your money and passport when traveling with bus (and of course in crowded places, but this is true for near the whole planet).
