No on-off switch. Press the button, the microcontroller wakes-up, simulates a rolling dice and stops. It sleep again afer 5 seconds. We cannot say how long the battery will last. More than three years by sure, we have three dices used for demos since 2015.
Of course, use a fine tip soldering Iron. For the small SMD - 0603, see the images from http://makezine.com/2009/01/12/surface-mount-soldering/ Put a drop of solder on one pad, bring the component close by with a fine tweezer, heat again and position. Put solder on the other side. Heat may propagate to the other side of the components, good, the component will self-center if you remove the soldering iron gently.
Use a minimum of solder, this mean use thin soldering Iron. 0.5mm max. We know you do not have thin solder wire, so we supply enough 0.3 mm solder - lead solder, more easy to solder. Do not worry, 0.2 g of lead solder will not kill you!
