I buy unscented baby wipes and TP. Most creams and powders are scented but I smell so bad after a few days, it probably doesn't matter and if I am chaffed, I do what I need to keep it under control.
My way out of the chafing and all that stuff is using an anti-chafing powder called Anti-Monkey Butt! It also helps absorb my sweat. ever since I started using it, I never had a problem again! It's good for workouts too!
I think I replied in this thread already, but I carry a handful of cotton balls in vaseline for fire starters. And if you get a chafe, voila, you have vaseline on an applicator. Taking care of it when you get back in camp? Take one out, rub the areas down, and then use that to start your fire.
