My white backgrounds come out bluish and are very uneven... getting tones of blues and reds and are
no longer 'white' as they are supposed to be.
Light shadows appear as red shadows instead of gray or black... and my digital pictures of close up jewelry... all look terrible. How can I control the my white background... so that it comes out a nice bright white... and that it is even throughout the photo.

This looks like a problem with your lightning setup.
It seems that somethings are refecting light on your object, since you have red and blue tones.
Try to avoid anything that can reflect in the area you take the picture, or at least to have a white surface to reflect, like to place some white, or black, cardboard around, but outside your object-area.
The same is with uneven lightning, try to improve your lightning situation.
To correct existing shots is for sure a labour intensive and not simple task, you may possibly try to create a mask of the object and then convert the background to b&w, to get rid of the color cast, then maybe some more masks and a gradient may help against the uneven lightning.
A general cast may be corrected with Filter or Color Correct.

But, as mentioned before, i would try to improve the lightening situation.

Hope that helps
