Great overview of women's concerns with discharge and possible infection down there! I've experienced my fair share of these issues and have found that following the tips you suggested have really helped. A lot of women I've talked to have good luck with regular ingestion of probiotics - either in food or in supplements - in keeping vaginal flora and yeast levels in the body balanced. Personally, I'm a big fan of my probiotic supplement! Oh, and thanks for pointing out that vaginal discharge at certain times during the month is normal in many cases.
