1) I always used Sudocream... it is the best, usually the rash would be gone after one application... not sure if it is available in your area, as I am in Canada, but deffinetly worth a look.
2) For as far as a night gown goes, I would just make sure it is something comfortable and with lots of room, and probably with buttons or a zipper down the front, for easy breast feeding. I just wore an over sized housecoat, and that worked out really well.
and I dont have an answer for #3, sorry. Hope I was able to help somewhat.... Oh and congrats on your pregnancy!!
