Hi, These are rather basic; I'd strongly suggest that you at least read An Intro to R, and maybe some of the other excellent beginner materials available. The answers are also easily available through Google, or RSiteSearch.

If you want more than one kind of symbol, you need to specify that - in your example you only gave pch 16, so that's all that is used. legend() doesn't "know" anything about your plot. You need something like: legend("right", legend=c("Model","Obs"), pch=c(1,2), lty=c(3,4)) > 4) how to add error bars (SE or STD) to an xy plot You can draw it yourself with segments(), but easier is to use errbar from the Hmisc package > The last is the most important for me right now.
