@Law. Your confusion reflects my initial confusion and my initial lukewarm response. I realize that the following advice may seem like a lot to demand of a player, especially for a machine on route. But like some other things in life, if you are willing to invest a little bit up front, you will discover there is more underneath.
1) Stop paying attention to the playfield insert lights. The general rule "aim for the blinky thing" doesn't work for WOZ because this is not a linear mode-based game. At any given time, several objectives are active which results in everything blinking.
Pay attention to the screen which keeps you apprised of the status of the main active items. To simplify things, you may want to play a game where you pay attention only to the upper right quadrant of the screen. See how far you can get with that. Then do another game you pay attention only to the upper left quadrant. Continue until you are comfortable with all four quadrants.
2) For a short cut to the above, download the WOZ owners manual, which is publicly available (http://www.jerseyjackpinball.com/game-specific-downloads/). There are pages explaining these rules in basic form. This 10 minute step turned me from a WOZ hater to a WOZ fan.

Yes, this is a lot to ask of a player. This is what you get with such a deep rule set. It's not even necessarily unique to WOZ. Spend 10 minutes studying the rule set and you'll discover one of the deepest (if not THE deepest) pinball machines ever made. Good luck.
