I just wanted to throw in my $0.02 on the philosophical issues.
A "person" includes a (complete) brain, which is built out of billions of neurons. The neurons must operate together "in concert" in order for the person to be functional. For someone to have a single coherent thought, many neurons must fire correctly, in response to their inputs, while many other neurons abstain from firing (equally correctly).
So, if neurons had "free will," they could just fire (or not fire) whenever they felt like it, with no concern over the rules that normally govern their firing. If neurons did this, a person's mind would just be pure static. They would sit around catatonic and periodically convulse. They would not be functional.
So, before a person can be free, they must be functional. And in order for a person to be functional, their neurons must not be free. And this applies to the lower layers of physics as well. They must behave consistently in order for these emergent phenomenon to happen, which means they must not be "free." (In the case of quantum randomness, the individual events are random but the likelihoods are not, and the raw numbers of interacting elements generate a statistical effect of consistent behavior which lacks any qualities of freedom).
Therefore, I think that the quest to find the building-blocks of free will in quantum effects, or really anything as-small-or-smaller than a neuron, is misguided. We would not expect those things to be free, because we need them to not be free, in order for us to exist at all (let alone think rationally). "Free will," whatever it may be, is a concept that can only logically apply to a neural cluster (or maybe an entire functioning brain).
Answering the question of whether or not free-will is real requires a very in-depth analysis on what we really mean by it, and THAT winds up being a wild ride unto itself. But whatever we decide it means, we can safely state that quantum particle/waves don't have it.
Oh, and about he question "is reality non-local." The answer there is: yes.
