I LOVE The Baby Book by Dr. Sears. It's great! I read it shortly before ds was born. There were a few things in it that I thought wouldn't be for me (like cosleeping)... until ds arrived and I learned better, lol! Besides the parenting philosophy that Dr. Sears espouses, though, it's an all-around good resource for medical advice, baby care, and child development.
Another good one is The Happiest Baby on the Block (author name escapes me at the moment, but you can find this one pretty easily).
For dealing with sleep issues, try The No Cry Sleep Solution by Elizabeth Pantley or Nighttime Parenting by Dr. Sears.
