I have the twin ring version of the 80-200 as you have just bought and also use it on a D7000.
I use it to shoot candid people and crowd shots at event for my event jobs.

(The DJ shots with nice bokeh and close up people shots in daylight were done with it - the exif data will all be there if you want to check as I swap lenses a bit)
And also use it for some car show type stuff:

It's a very good lens, really sharp, great colours and contrast.
I always use it with a centre point focus on the D7000 and find it locks on quickly and rarely misses with focus.
I tend to shoot it wide open at 2.8 all the time to keep the shutter speed up and ISO down.
Here's a tip: set up one of your U1/U2 modes specifically for this lens! No VR so shake will be an issue so set up a mode for a minimum shutter speed of 1/250, aperture priority, and auto ISO.
That way you can shoot away knowing that it will always be minimum 1/250 in that mode.
Trust me, a grainy photo due to higher ISO is much better than a blurry one!
My only beef with this lens is that it really is a bit too 'long' on a crop camera, unless its telephoto reach you need for sports/wildlife etc.
If you are shooting people or cars then you have to be quite some way back to get them in the frame!
Forget shooting head to feet shots of people unless you are outside and can step back a good 10 meters or so...
One of the reasons I'm considering a D600.
But for clarity, detail and bokeh it's a cracking lens!
I'm vain so I put the new style 70-200 hood on it!
