The definitive Blender site to start with would be http://www.blenderartists.org.
The documentation site, http://wiki.blender.org also contains links to many hours of good video tutorials. (I am particularly impressed with the ones at http://www.blendercookie.com.)
By now, most of the techniques you’ll encounter with any package have also been implemented to some degree in Blender. (Although I realize that, had I made this comment in any other thread but here, it might quickly bring out a list of things that Blender doesn’t do, that only “package thus-and-such can do,” which list is obviously correct.) So, you can expand your self-study almost in any direction and not find yourself saying, “gee, that’s nice, but Blender can’t do this.” (At the very least, you’d have to add the last word: “… yet.”)
I am personally of the thought that it makes a lot more sense to focus your attention on “what you can do (using a tool),” rather than on “what the knobs and buttons do.” (I’d say that for any product … and not just a CG product.) Once you understand what you’re aiming at and how to get there, well, first of all you’ll realize that TMTOWTDI.
Then, you’ll be able to find the knobs and buttons that you need “to do it” in the way that you select.
Footnote: what’s the Python equivalent of “Tom Toady?”
