Power Plane and Decoupling Capacitors Routing
If the IC's power and ground pins and the bypass capacitor power and ground pins are all directly connected to the appropriate planes, you don't need any tracks on the non-plane layers to make the power and ground connections.

The power and ground planes themselves make a fairly good bypass capacitor, in addition to any capacitors you add.

If there are high-current devices on the board, you should arrange things so that there are no sensitive circuits between the high-current device and the power input connections.
