This does not fully answer your question, but there is a function col2grey (or col2gray) in the TeachingDemos package that will help you see what a given color plot will look like (approximately) when printed/photocopied in grayscale.
For your example you would do something like: > plot(1:6,col=col2grey(c(1,7,5,3,2,4)),pch=c(1,20,20,20,20,20)) To view the grayscale version of the plot, then try with different colors until you are happy with the results.
