This probably does not answer the full question, but you may want to start by looking at the RgoogleMaps package which will download maps from google, plot them, and overlay your data on the map.

EK,

This has a number of steps, including importing, re-projecting, filtering, plotting (with your choice of background etc), so

I'd start with a quick look at http://cran.csiro.au/web/views/Spatial.html, 

then in R type :
Then get down to the library or bookshop and get a copy of 

Bivand, R. S., Pebesma, E. J., & Gomez-Rubio, V. (2008). Applied spatial data analysis with R. Use R!, Use R! Series (p. 378). Springer.

cheers

Ben
