i read up on programing manual primes on the d7000 or other DSLR that allow metering for them. I know how to change the settings on the camera depending on what lens is mounted.
I looked up about zooms and could not find out enough answers. One article said program as many sizes as you want if you have a zoom.
Do you have to constantly look at the zoom to know what mm you have at that moment then program the camera and shoot. I think I would miss many shots with this workflow.
Is there any easier way to conquer this scenario? Basically I want to shoot and not have to look at the zoom body to make my correct settings.

From what little shooting I have done with manual lenses on my DSLRs, the camera settings are used only for writing the EXIF data into the image. However, matrix metering and shutter-priority mode both want to know what the max aperture is. Other modes don't care so much, at least on my cameras according to some books.
I don't have any manual zooms, but if I did I would try programming the camera with the smallest variable aperture (f/5.6 on a f/3.2-5.6 lens) and pick a middle focal-length number. If that worked well enough, I would stop there.
Hopefully someone with more knowledge on this will chime in.

I owned a Nikon 75-150mm f/3.5 manual lens for awhile that I used on a D300. I set the focal length to 100mm as there wasn't another that matched (no 75 or 150mm in the menu choices). I set the aperture to f/3.5 as this is a fixed aperture lens, but I think Joseph's suggestion of setting to the smallest max aperture for a variable aperture zoom would work fine. It doesn't really matter that much what focal length you use, but choose one that differentiates it from other lenses you have so you'll know when looking at the EXIF data what lens you used. For example, don't use 105mm if you have another 105mm. It would be way too much bother to set up a number of focal lengths for a zoom and wouldn't improve the functionality of the lens.

I just purchased a 80-200mm manual f4.5 converted AI zoom and will set it to f4.5 since it is not variable and pick a mm that is not one of the primes that I will be using with the DSLR. Thank you all for your help.

Joseph and Alan have it right. It is best to set the lens info when you mount it. That gives the matrix meter an understanding of the maximum aperture, and the EXIF info will be basically OK. Put in something for focal length that will allow you to identify the lens later. You can't really keep up with setting the focal length for each shot. As you say that would be too much work. The result is that the EXIF information for focal length will not be accurate, but it's certainly no worse than the situation we had with film - which had no EXIF information at all. (OK, with a data back, perhaps we had date.)
Normally I use only manual focus primes, and in fact I only use two that have no chip very often. They're a 35mm and a 500mm, and I don't switch between them very often, so I can set it once in a trip and forget it as I change lenses with my mostly AF and other CPU lenses.
