There aren't many creative options with E-6 processing in general, so there isn't as much reason for there to be a popular book on the subject, though I'm sure there are some very technical books on E-6. Just get one of the kits, and follow the directions carefully. With B&W you can experiment more, because you don't have to worry about color shifts.
As the others suggest, start with B&W just to get used to handling film, agitation, and the basics.
For E-6, I've had good results with the Tetenal 3-bath kit, which is convenient for normal processing and one-stop push processing with Kodak and Fuji films. I recommend using it one-shot for push processing, or reusing only once for normal processing, although they give instructions for running three batches through one set of working solutions.
For more control or greater than one stop push, the Kodak and Tetenal 6-bath kits are better.
