Composition dolls help?

MMkay I am going to be dealing with several compo dolls from the 50s. They aren't in "collector's condition" because they were quite loved but I'd like to figure out if something can be done to cheer them up a bit. I would like to know any and all things that can be done to make them pretty again.
1 They stink, literally. Is there anything that can be done so they don't smell so sour and musty?
2 Their finish is crackled/chipped/dinged and some fingers are missing. Not that much of a problem if I can clean them up.
3 They need to be restrung, how isn't the problem so much as what to use.
