For a), if you really want the plots overlayed, it is best to use something like matplot, or use the points or lines function to add the later plots to the first. You can also get the overlay effect using par(new=TRUE), but then you need to be careful with axis labels and scales and the plot may end up being more confusing then helpful.
For b), if you are just doing a quick exploration of the plot, there is the zoomplot function in the TeachingDemos package that may work for you. If you want a plot to print/save, it is best to specify xlim and ylim in the initial plotting function to create it at the correct size/zoom from the beginning. Hope this helps, -- Gregory (Greg) L.
