first: I would not use the 164, its outputs dont latch and unless your very fast and cute about it what will happen is you will see the bits stream in on your leds in real time causing all kinds of ghosting, something like a 595 is better cause you can stream the bits in to a buffer and once everything is in place flip a switch to show the end result.
second: normal 74xxXX series chips are not that great at handling current,there are better solutions out there
third: you can daisy chain shift registers, most of them have 1 extra output which you feed into the next chip's input making them expandable to large degrees.
