Mark,
pretty difficult to answer this without causing a flamewar... well,
let's try:

One thing that I am confused about is the role of the Core Foundation

they something that for the foreseeable future Cocoa and Carbon will
both use? As a programmer new to Macs, should I look for alternatives
in the BSD libraries and Cocoa frameworks? Or is CF still the
apple-preferred way to do some things?
Originally, Cocoa -- called OpenStep then -- was completely
object-oriented. Later though Apple decided to create an alternative
API, (so far as possible) just with the same strength, but *not*
object-oriented, called Carbon. Let's not discuss whys, let's stay at
that it's exactly what happened.
To be able to do so without implementing really *many* things twice,
they had to create a non-object-oriented intermediate level, which is
then used in Cocoa and in Carbon both. That's Core Foundation.
