Sometimes you just can't beat having a couple of LEDs at hand that you don't have to wire up with resistors and millions of wires. These here just work in either common-anode or common-cathode configuration. Plug the board into the breadboard and simply connect the common pin to GND or the positive supply voltage and drive the individual LEDs by sourcing or sinking current. It's up to you ;-)
Why 2 rows of LEDs for only 8 channels? Simple! If you use the common-anode configuration, one row lights up. If you use the common-cathode configuration, the other row lights up. This eliminates the need to do any rewiring on the indicator board itself. It just works.
The LED orientation doesn't really matter, as long as it is the same for all of them. If you want a certain row to light up when wired up in a certain way, solder the resistor-arrays first and use one of the SMD LEDs to probe for the correct orientation. Use plenty of flux. Paste / gel usually works better than flux-pens.
