I went to check on your behalf, and Annual Dues (and historical info) is literally Chapter 1 of the DVCFieldGuide which a number of people have recommended to you. I think if you get it and just read thru the Chapter Titles you'll see a lot of topics you've not even asked about (sometimes we don't know what we don't know). If you look thru that it might give you a better overview.
If you are just "curious" about buying DVC I'd ask questions here, but spending $15 on something that pulls it all into a practical format would be a ridiculously small investment if you are at all serious. And a lot of what is in there is used by old-timers for every trip they plan long after they've bought contracts.
To put it another way, feel free to ask questions, but I'd be asking the questions I'm confused about, not the basics you can learn from a simple publication. And to clarify, that guide exists because to get the basic info you'd have to ask 100's of questions and visit a number of sites. And you'd still likely get some wrong or outdated info on the web
