All three questions in section 6 in the R FAQ details R and (X)Emacs.  And
yes, you do want to learn ESS as that is how (X)Emacs and R play together.

Put 

	options("width"=160)       # or whatever nb of columns you want

into ~/.Rprofile.  You may want to set other preferences too, see

	help("options")
	help("Startup")

Good luck,  Dirk
