Once in DV, you may want to check out Skidoo. It's a few miles off the Wildrose road, south of Stovepipe. The elevation isn't too extreme, so the road should hopefully be open and in decent shape. There's not much left of the town, but there are several neat rock mills still standing.
The Eastern California Museum in Independence has a large collection of wildly photogenic old farm equipment, cars, mining equipment, etc. From there, continue west on Onion Valley Road as far as conditions will allow. It's a very pretty drive.
Don't forget Ballarat in southern Panamint Valley. Not far away is the city of Trona, which I find strangely appealing. It's got the industrial mining town look (because that's exactly what it is!)
