I had a question about ISO. Is there any way to put the ISO in AUTO when i am using Modes A,S,M?

Yes! Go into the camera menu:
Shooting menu >
ISO Sensitivity >
Auto ISO Sensitivity Control > "ON"
Then set the Maximum ISO sensitivity >
and set a Minimum Shutter Speed
See page 103 of the D7000 Users Manual
Good Luck and Enjoy your Nikons!

Yes, as Marty says. The degree of control you have is slightly different when ISO Auto is engaged, depending on which mode you are in...
In "A" Mode, you choose an aperture and a base ISO value, and the camera will choose the appropriate shutter speed for the illumination level. If the shutter speed would be slower than the minimum you have set, the camera will raise the ISO and continue to do so if it gets darker until the ISO gets to the maximum you set, then the shutter speed will be reduced below the minimum you set.
In "S" mode, you choose a shutter speed and a base ISO value, and the camera will select the appropriate aperture. If it gets darker and the aperture needed reaches the maximum of the lens, the camera will raise the ISO until it gets to the maximum you set and then it can go no further.
In "M" mode, you choose an aperture and shutter speed, and the camera will select the appropriate ISO, between 100 and the maximum you set.

The short answer is "yes," and the long answer is "maybe." Auto ISO is probably better than setting it at ISO 2500 for no particular reason. ISO 2500 is generally for low light photos, and if you were taking a picture on a sunny day, and forced your camera to use ISO 2500, your picture would show more noise than was necessary considering the lighting conditions and might force you to over expose your picture. It would also limit your ability to control depth of field. I think that some other posters have recommended some books that make this concept more understanable, and would also enhance your appreciation and abilities in the long run. There are no dumb questions, only dumb answers.

To amplify jpFoto, in aperture priority, Auto-ISO gives you the LOWEST POSSIBLE ISO for the minimum shutter speed that you tell the camera you will accept.
Lowest possible ISO means best possible image quality. Ergo Auto-ISO delivers the best possible image quality (for the minimum shutter speed you will accept).

I use either my 10-24mm or 18-105
focal length would be 40-60mm...
Not sure how good my holding technique is...

Is there an all around good shutter speed? I assume this wouldnt matter if I use "S" or "M" mode right? The min. shutter speed would be if i used mode "A" correct?

The Rule of Thumb for Minimum hand held shutter speed with a DX body is:
Minimum Shutter Speed = 1/ 1.5 X Focal Length of Lens
Minimum Shutter Speed = 1/ 1.5 X 60mm
Minimum Shutter Speed = 1/ 90th sec.
With good hand holding technique and or a VR lens the minimum shutter speed can be 1/30th sec. or possibly slower.
