Chain coming of jockey wheel when pedalling backwards

Hi

When I pedal backwards my chain instantly comes off the jockey wheels on my rear mech.

I am thinking its because my cables are a bit gunged up and the rear mech is a bit sticky. I was going to take the rear mech off completley and replace the inner/outer cables.

My question:

When I take the rear mech off and replace with new cables, how do I go about ensuring it is indexed correctly? Presumably the Hi & Low stops will be fine, its just the inital tension I put on the cables..

Any ideas?

Thanks
