The TEA5760UK looks like a better documented and easier to use chip, still only about 3mm square. A 2-layer thin (0.6-0.8mm) board with components on both sides seems like a good idea. The FM radio chip doesn't need much in the way of external components, but you'll probably want a small microcontroller to handle buttons for tuning and volume, a headphone amp, and maybe battery management and/or voltage regulation.
