I am quite familiar with all of these references. The theory behind LDA is not where the problem is - I'm comfortable with that. The problem is that I do not know what R is computing when it prints "Coefficients of linear discriminants". (According to the source code (lda.R), it's x$scaling, but I don't know what that is either.)
