Or is the output of the little eBay strain gauge amps already serial
so if it was a 24 bit device (16777216) it would be resolving down to
~1/3000 of a g (mathematically at least) and so would just use the
Arduino to turn it into ASCII over a USB interface (no ADC needed)?

If you find the data sheet for the device you may find that the lower
bits are effectively noise and you need to be averaging multiple readings.
