I would say focus more on the voltage rating. Capacitors don''t really dissipate a lot of real power when used well under their voltage rating. They do though however generate reactive power but that has nothing to do with real power and hence heat. Voltage rating is more important than ''power'' rating. $endgroup$ –

One capacitor per power pin. A good IC pinout will have a ground pin next to each power pin, so you can keep the loop as short as possible. For low-power ICs 10nF capacitors may be sufficient and may be preferred over the 100nF because of their lower internal inductance. For this reason you also find 10nF parallel to the 100nF.
