I think the JW position is a rather confused mish-mash of all three options that you mention. God has the "super-power" of seeing the future (which is distinct from the God of mainstream Christianity who knows all things by his nature), much as Clark Kent has the super-power of seeing through solid objects with his X-Ray Vision. Just as Clark can choose not to look through the wall into the girls' locker room, God can choose not to see the outcomes that will be brought about by the free acts of human beings (as if there were such libertarian freedom). This is a form of a doctrine that pops up here and there in evangelicalism called "Open Theism." For this reason, Jehovah doesn't know who will be saved and who will not, because he has chosen not to look. JWs have a God who can be surprised. So when God said (after Abraham as much as offered up Isaac), "NOW I KNOW that you are God-fearing, in that you have not withheld your only son from me," it was because God really didn't know what Abraham would do (Gen. 22:12). This does create a bit of a conundrum for the JW, however, since, if taken as anything other than an anthropomorphism, this verse not only implies that God does not know the future, but doesn't even know the present, since the implication is that he was unaware of the present condition of Abraham's heart.
However, in JWism, Jehovah can also maneuver the events of the future if he wishes to in order to accomplish his purpose. Pharoah, Nebuchadnezzar and Cyrus were all people that God specifically said would carry out certain actions relative to Israel. Did he thus deprive them of their free will? What if Cyrus didn't want to conquer Babylon? How would the Israelites been freed from bondage? God had specifically named Cyrus in Isaiah's prophecy, well before Cyrus' birth. What happened to Cyrus' free will? Apparently Jehovah overrides the free will of some people in order to carry out his purposes. Seems rather unfair, when viewed through a JW lens. The image one actually gets from JW literature, though, is of God as a master chess player who, while not directly overriding free will, maneuvers external factors to the individual in order to cause him to behave in the desired manner.
In short, I think you are trying to make sense of a JW doctrine the implications of which have never been fully explained by the organization, that is not understood by JWs themselves, and that is internally inconsistent.
