The principle is correct.

As AndrewT stated, it is all in the datasheet

If you don't use it, no music will come out of the amplifier. You need to connect at least a resistor to V- there. The size of it depends on the rail voltage you use. The formula is in the datasheet.

Parallel application was already planned for this PCB, because there is a place for the load sharing resistor (R1). On the other hand it looks, as if there is only space for small Cs on board and the 100 nF decoupling caps will have to be soldered directly to the IC pins, because there is no place for them.
