Firstly, keep learning! It is a fun hobby, honestly.
You see the 'shaded box' attached to the top, right side pin of your Arduino with one line? Inline with the LED modules. That can go.
Second, the pupose of the sink drivers is that each row of LEDs on the modules is never on at the same time. The Arduino pulses each channel in sequence at a fast rate to look like their on all the time, as you send data to the shift registers.
Third, as only 1 row of the modules are on at one time, the total usage of current is a maximum of 800ma.
10ma * 8 * 10 = 800ma
Fourth, each channel of the sink drivers can sink 500ma. You can parallel the channels for higher current handling.
