I was just browsing through the guide to add on packages and found Graphics`MultipleListPlot` and Graphics`Legend` and Graphics`ErrorListPlot` which do automatic error bars and annotations. I think drawing an arrow to an exact feature of the plot would still take a little programming with graphics primitives though.
