You generally will want to play an easier song that you know you can be pretty accurate on, and then change the graph in the results screen to the accuracy graph ( ">" button next to graph in results).

You will want to adjust your global offset until the audio makes sense to you and aligns with when you hit the note (it can change from song to song, some really old songs have some really bad sync), and adjust judge offset until the graph looks something like this:



You want the majority of notes in the middle of the graph. If it's not aligned in the center, you should adjust it. Setting 'Auto' for judge offset can also help.
