Your lines should be represented by the Polyline primitives. Check the Row property of the polyline to see which datarow its data came from. This would only apply to the lines that get drawn by the chart, and not the lines you drew yourself using FillSceneGraph.
The custom pallette is just a color array. If you know the color index, you can use chart.ColorModel.CustomPallette[index] to get a color.
