If I remember correctly, Diana Stride (yes she was the TV Journalist, who was played by Rachel Welch) lured Superman to her penthouse by staging a fire and calling for help. This allowed her to plant the tracer on Superman which lead her to the Daily Planet.

Intergang once used some sort of tiny rockets loaded with paint to show Superman that he couldn't protect everyone. While Superman was able to stop the one heading for Lois, Jimmy was splatted.
