I am from Australia, and the nearest Acorn book is probably further away
from me than Woop-Woop, so could someone please (just briefly) enlighten
me about the 4 graphing calculator skills that students are expected to
be able to perform?

And, are graphing calculators being used mainly to develop concepts, via
investigations, or are they replacing traditional skills? For example,
would an AP-Calc student with a graphing calculator be expected to be
able to sketch the graph of, say, (2-x)/sqrt(1 - x^2) _without_ a GC,
by determining the domain of x, finding the y-intercept, and looking at
the behavior of the function near the values of +-1?
