If you're going during the first week, the grounds pass is all you'll need to see enough good tennis to satisfy anyone. AA has the marquee matches, but they're usually beat-downs, and you'll be so far away you won't see the ball.
I suggest not bringing in a bag (ie wife's shoulder bag) because it's a long line to get through.
