If I was starting again here's my list in order for books:
How to Brew / Palmer (great introduction to all grain topics, great layout, easy reading)
Designing great beers / Daniels (name's pretty obvious here)
Brew Chem 101 / Jonson (skip if you've got a degree in biochem, but helped me a lot to understand the next book)
New Brewing Lager Beer / Noonan (science!!)
But I've learned the most by far from asking knowledgeable brewer's. Join a club and nerd out about your beer.
