I am going to suggest something that will not be popular but would be very useful. Read the D7000 manual from cover to cover and the nature of the subsystems and their relation to each other will be covered at least on the function level. Some people like the aftermarket books but all you really need is in the Nikon manual.
If you have the fundamentals of light, color and time down, all you need to do is brush up on the functions specific to the D7000 and the manual is pretty good.
Specs are interesting to consider on cold windy winter nights but the only thing that really matters is results and how predictably your intentions are realized with photos. Regardless of knowing the technical details or specs, AF tests notwithstanding, you got an image that looks very good, is interesting and worth viewing so that transcends specs every time. Most gear heads never get past the spec part and never produce images that anyone other than their mother would love.
