I think you will be disappointed if you connect all those LEDs in parallel. Some may burn out, and you'll see uneven brightnesses. You will need a separate resistor for every leg of every LED, and still, the current control features of the ShiftBar would not be used correctly. Usually the best way to connect a lot of discrete LEDs to a ShiftBar is to connect them in series with a higher voltage, but you can't do that with common-anode RGB LEDs.
