I have not seen this documented anywhere. The closest thing is the default settings on the I/O tab of the driver station.

eg: there are 8 analog inputs on the board, but only 4 in the default "DS Compatibility" interface.... so.. I'm to assume that we only use analog channels 1,2,3 & 4 on the Cypress board??

First 4, yes.

But what about the digital channels.
DS Compatibility interface has 8 digital inputs and 8 digital outputs.
It "appears" that cypress digital channels 1-8 corrospond to the inputs, and 9-16 corrospond to the outputs, but I'm just guessing....

This is accurate with what we have observed and used in the past. The first 8 are inputs (I believe pulled up or floating, I don't recall which - last year's DS was floating, so that would be closest match, but I seem to recall observing these as pulled up).
The second 8 are outputs.
Note that if you were to move to the enhanced I/O configuration, you can make a definitive selection of each pin assignment, control direction of pull (or floating) on inputs, eliminating any doubt and guesswork.
