As far as books, there was this little guide I got inside when I purchased my son's potty which was very helpful - it's from Johnson's (you know the same ones who have the baby powder) - it's called Johnson's Everyday Babycare Potty Training - it has all kinds of tips for almost every aspect of the potty training process. You can check this link http://cn.dk.com/nf/Book/BookDisplay/0,,9780756605674,00....
also, check out www.pullups.com - they have stories from parents, tips, videos (even a free DVD that they can send to you) and it takes you through each phase of potty training. There's even charts to personalize & print out for if rewards become a part of the process!
In my opinion, knowing the signs of readyness is most important...as well as having LOTS of patience through it all.
I was quite frustrated at a time & stated how I didn't think my son would ever be potty trained. Then I received one of the funniest lines I've heard from another parent about potty training - she said "unless the person has special needs, have you ever seen a grown man or woman that didn't know how to pee or poop?"
So...with that...Good Luck! It'll all happen as it's supposed to!
