Prevention is better than cure!! If you use treated timber & galvanised screws then these wont rot or rust..........but that doesnt escape the fact that they are being used in a damp area.Address the problem of the source of dampness.As breezer states,fit some form of ventilation.
Finger in the air I'd say you need to dig a trench down the side of the cellar wall (on the outside), apply a membrane and treatment to the outside of the wall and install a land drain.
If water is upwelling into the cellar through the floor then it might be worth installing a sump and pump.
I once had a damp cellar - stored some wine in it, all the labels rotted and fell off - had to drink it to find out what sort it was.... Solved the problem by fitting an extractor fan to pull air from the cellar to outside, and setting a timeswitch so that it came on automatically for an hour a day. Problem solved !
