Almost 17 weeks and first time mom. Can anyone recommend any books or articles online that give the ins and outs of breast feeding/pumping?

I will be going back to work full time 8 weeks after baby is born and was feeling pretty nervous about breast feeding in general. I have a lot of questions about pumping, storage, what kind of bottles to use with baby, etc. At first I was nervous about pumping at work but I am beginning to come around to the idea knowing how good breast milk is for baby as well as money saving, but I am clueless and want to take all the time I can to prepare myself. We started putting items on our registry also so any must have suggestions are appreciated. 😊
