If  you have a clear 1024x768 image, cropping it to 1000x600 shouldn't affect image quality unless your jpg save options are set low, make sure thay are at 100% quality.

You should be able to just grab a 1000x600 rectangle of the area you want using the curser, crop it with the crop command, and save it,  You shouldn't have to "re-size" anything as the original image is bigger than what you want. Hope this helps.
