The capacitor is not essential in most cases. If you see erratic behavior when moving multiple servos at once, you can add some capacitance. Something like a 470-1000uF @6v or more is a good value to start with.
To connect 2 or more in series, just chain the 6-pins one the end of the board to the next board. A 6-pin cable like this makes it easy. Use a bit of solder to bridge the address jumpers on the upper right of the board. For 2 boards, just bridge A0 on the second board. Its I2C address will then be 0x41.
