When it comes to Voodoo, there aren't many books or websites out there that give good information given the fact that there are so many misconceptions about the religion in general. The best thing I can recommend you to do is find a spiritual community near your area and allow them to guide you, although many practitioners are solitary, Voodoo is a community religion. Stay away from authors such as Denise Alvarado, there are good books on the subject; the thing is to find them. The first thing to understand when it comes to Voodoo, is the difference between Vodou and Voodoo. Voodoo is a creolized version of Haitian Vodou, Voodoo having major differences such as the focus on Danbalah.
Here is a book I recommend for reading on Haitian Vodou:
Haitian Vodou - An Introduction to Haiti's Indigenous Spiritual Tradition by Mambo Chita Tann
As towards hoodoo, it has nothing to do with Voodoo and this is something to keep in mind. Hoodoo is a folk magic practice which is a mixture of native american magic, european elements, and even jewish mysticism. It is a practice that has no deities but is a concentration on personal power, the absence of any deity or spiritual force. When Hoodoo begins becoming mixed with other practice/religions it ceases to be Hoodoo, remember that.
For hoodoo resources, Starr Casas has a couple of good books on the practice. The thing to remember when reading up on rootwork is that every practitioner works in a different manner and has a different way of doing things, there is no right or wrong when it comes to the practice as everyone likes to add they're own spice into the cauldron.
Best of luck on your path
