I also wanted to add: If you are regularly wearing any nursing pads, I found the disposables to be more gentle on my traumatized nipples (harder on the environment, I know.) Even now, the cloth ones stick to my nipples when I take them out of my bra and it can be irritating to the sensitive skin. I think those may be better since you're battling thrush, too. You want to keep the moisture off your nipples and disposables do a better job of that (though if anyone knows of any cloth pads that are any good, PLEASE let me know!)
If you can, try to spend some time every day without a shirt or bra on, just letting your skin breathe. I've heard it's good to let sunlight on your nipples- maybe if you've got a nice fenced yard and live where it's warmer than 45 degrees.
