I have found autofocus (AF-A) works well enough so I hardly use the other modes. And it switches to AF
-C automatically as needed for moving objects. I also use all the focus points (39) and have never had the need to switch.
Some people have encountered a known tendency of this body to back-focus at times but I haven't had those problems as pronounced as others since the majority of my shots are sharp. Just be sure to update the firmware to the latest.
For metering I use matrix most of the time. The only downside is a slight tendency of the sensor to overexpose in bright sunlight. Using manual mode or negative compensation (S and A priority modes) usually takes care of that issue. Switching to spot or center weighted metering also helps but at the risk of underexposure in some shots.
The d7000 body is nothing short of superb for its class but you have to have really good glass to take full advantage of it. Also the noise and color performance are very good. Many of my shots require very little NR and usually no color enhancement. You should be happy with it.
