congratulations!
Good on you. I don't understand people on here who say they never read parenting books...what? Never do any reading about the most important thing you will do in your life? I wouldn't even walk in to a restaurant without reading the menu first! The irony never escapes me that they are saying this on a parenting website! Maybe it's just paper they don't like. 
Anyway, what i'd suggest is that before you commit yourself to lots of books. Look around the web (even just mn) and get an idea of what kind of parenting you think you'd like to follow. Reading threads about them will help you see how they work in real life, eg lots of mums to be are sucked in by gina ford/baby whisperer routine type books, only to find they heart breakingly unworkably when their lo arrives.
I'll suggest some starting points though this will be coloured by my parenting style so hopefully others will come along and redress the balance. 
So to start with look in to attachment theory by bowlby (google it) aka why the "rod foryour back" thing is bull, and dr sears' attachment parenting which is related but not the same iyswim.
Actually to rewind (i'd recommend Ina May Gaskin's guide to childbirth in prep for the big day and lots of reading of the mn bf/ff board for feeding info. It's invaluable.
I'm a big fan of Unconditional parenting aka "why your 'instinct' isn't always right" (by alfie kohn) and while it is one where i'd say it's worth reading the book there is an Unconditional Parenting support thread somewhere on mn (again use the search facility) that gives you an idea of how the theory works in real life so check that out first.
At the other end of the parenting spectrum there is stuff based on skinners developments of behaviourism (think time out etc) though please read up on this as it's amazing how often i see people talking about it on here with so little understanding of it. imo it's worth noting that skinner himself rejected the use of time out...
Other things i barely knew about while pg but now do/did include cosleeping, baby led weaning and elimination communication...maybe they are for you too? Have a read and see!
