Trial and Error
Most of what you will learn will come from going out doing it and seeing what works and what does not. Like other have suggested "Freedom of the Hills" is a great book, but somthing I picked up lately and has some great advise as far as eating and clothing options is Mark Twights Extreme Alpinism. While alot of the book is far more extreme than anything I do, I like to apply some of his thoughts and theories to what I do.
As far as advise, learn your clothing system quickly. That is one of the quickest things to ruin a trip is if you are either too hot with too many layers, or freezing from not enough. Nothing is worse than going out on a subzero day with every article of clothing you own and sweating your a$$ off then stripping down only to freeze on your sweat soaked fleece.
