Personally, for a novice, I think the SAS course 'Data Mining for Enterprise Miner' is an excellent all round introduction. If you can't get to a course, I think they sell the course notes.
As for books, one thing you need to consider is whether you have the server or client version. They are not the same, quite a bit is different. I bought a segmentation book that looks like it for the server version and I use the client version. I will be giving the book a crack this year, not sure how the differences will affect me.
I really like Matignon's Book as a reference
.
