Welcome Celeste. Glad to have you aboard.
As far as books, I've never bought one single book on Whole Foods. Everything I learned about eating the whole food way I found online. I read articles, researched recipes..etc. Maybe someone will come along after me with some book ideas, but I really was too cheap to spend money on books.
It really isn't that complicated of a way of eating if you keep in mind the following types of foods: lean meats, whole grains, scads of veggies, fruit, good fats, low fat dairy. And of course exercise and lots of water!
For me, I primarily eat chicken breasts and all sorts of fish, beans, wonderful whole grains like bulgur wheat, quinoa, brown rice, whole wheat couscous, any bread I eat is whole wheat, olive oil and canola oil are my two primary fat sources, I eat 5+ servings of fresh veggies a day and desserts in my house are either fresh fruit or microwave popcorn, in a popper not in the bags. Whole foods doesn't mean you can eat as much as you want, however. You still need to practice portion control. Some weigh their foods, some count calories, some combine the whole foods approach with Weight watches or some other plan.
A couple of the plans that have a whole food emphasis are the Medieterranean diet and the Sonoma Diet. If you Google these, you should come up with a lot of information.
