If you do decide to sell it separately, do not split items that originally were a kit.
A body, for instance, must be sold together with a focusing screen, finder (folding waist level finder), and wind knob/crank. A magazine complete, and together with the slide.
Retracting a bid on eBay is hard, if not impossible. So that right order thing may not matter much.
No need to retract anything. If the camera body slips away you just don't bid on the other equipment. That's why order is important.
