See the podcasts here, several regarding supplements:

I think the one on magnesium and the one on alpha-lipoic acid and acetyl-l-carnitine are very important.
Also there is an image here titled Nutrients for Neuropathy that I copied from a book I had (let me know if you can't get to these):

Personally, alpha-lipoic acid and evening primrose oil help with my pain. Magnesium is a good candidate as well--magnesium citrate for example.
