For number 1, one option is to use the setHook function with the hook in
plot.new. Using this you can create a function that will be called before
every new plot is created, your function could then call par with the options
that you want, this will set the parameters on all devices. However it could
cause problems if you ever wanted to change those values for a plot, your call
to par would be overwritten by the hook function.
For number 2, S-PLUS did have the default to warn when points were outside the
plotting region, this was annoying when people intentionally used the limits to
look at only part of the data, so I don't think it would be popular to bring
back this behavior in general. You can use the zoomplot function in the
TeachingDemos package to expand the range of your current plot to show data
that was outside the limits, or I believe that if you use ggplot2 the plots
will be expanded automatically to include all the data (unless you limit the
range in the call). You could also write your own points or plot function that
would check the range and give warnings then call the regular points or plot
function.
