In addition to Wikipedia, the MDN also has a few good introductions to SSL, as the Mozilla foundation sponsors NSS and an assortment of other PKI projects.
If you're looking for an all around SSL/TLS book, SSL and TLS: Designing and Building Secure Systems would be a good choice, as it discusses the workings of SSL, its strengths and limitations, as well as safe design patterns for implementing SSL across a variety of applications, including web servers and email clients.
You can also check out the Open-Source PKI Book, which is a free open source book on the various open source PKI implementations.
The problem with a book on SSL management is that SSL is used for so many different purposes and with so many different applications. How you set up or manage SSL certificates for web servers depends on what web server, OS and other PKI software you're using.
A lot of CAs and vendors (IBM, Symantec, Trustwave, Microsoft, etc.) have whitepapers and tutorials on certificate lifecycle management for large organizations, but they're usually tied to the specific certificate/PKI management product they're selling.
I suggest getting a basic understanding of how SSL works (how asymmetric encryption works, what is SSL/TLS designed to protect against, the architecture of PKI), then from there narrow it down to the specific application and usage scenario you're interested in and what solutions are available for it. Then you can just study the manuals and tutorials about those specific products, like:
And you'll have a much easier time finding detailed information from beginner to advanced.
