At six weeks, there should be minimal pain when nursing, and that would only be during or right after latching.
First, don't use cabbage leaves! This is a homeopathic way to decrease milk supply when weaning. So unless that is your goal...
Also, I would recommend against shields unless absolutely necessary. They can be difficult to transition away from.
Lanolin is good.
Also, try expressing an extra few drops at the end of a nursing session and rub it in. Breast milk has great healing and anti-bacterial properties!
Avoid using anything that will require being wiped off before nursing (vaseline, chapstick) - that's just more friction on an already sore spot. Also, no matter how you wipe, there will likely be a residue that your baby may/may not suck off as he nurses.
You said that you're certain his latch is good. I would still wonder though. Poor latch is the #1 cause of sore nipples. One advice giver said that she wishes LCs wouldn't blame poor latch so much since sore nipples are so common....well, poor latch is common, too! Look at your nipple when he first unlatches. Is it pink and round? Or white and/pinched looking? If it's the latter at all then that indicates poor latch. Be sure that his tongue protrudes over his lower gums when he latches and while he's nursing. You should be able to pull back his bottom lip while he's nursing to check this. If pulling back his bottom lip breaks the suction, then it's latch...
Have you recently started pumping? Sometimes if the 'horn' of the pump is the wrong size it can cause sorenes.
If your nipples become dry/cracked, I would avoid doing anything extra to dry them out. It just doesn't make sense to me. If my hands are dry with the knuckles cracked (which happens in winter) I don't add heat or anything to dry them out more -- I add lots of lotions and creams! Made sense to me to do the same on my nipples when this happened with my first baby.
Is it possible that it's caused by thrush? I've never had thrush, but I know it can cause sore nipples. Does he have white towards the tip of his tongue that can't be (easily) scratched off? Your local LLL leader can help you identify whether or not you and ds have it.
More than anything, please please please contact your local LLL person - this is why they are there - and it's FREE!

If you go to their website, you can find phone numbers to contact your local leaders. You do not need to wait for a meeting to talk to them. I know they do phone consults and I know some leaders who do house calls on a regular basis.
