Answer 2

Introductory Statistics with R (Statistics and Computing) (Paperback) by Peter Dalgaard

Answer 3

See the StackOverflow question Books for learning the R language

Answer 4

I've bought several books, including Dalgaard's, but my preferred text is Venables and Ripley's Modern Applied Statistics with S.

Lest the name deceive you, this book -- now in it's 4th edition -- is as much (if not more) about R than about Splus (both of which are implementations of S).
