I second scanner's recommendation of NPH 400, NPC 160 and NPS 160. These are films specially designed for portraiture use, and renders skintones very well. They are low contrast, low saturation films so they can hold shadow and highlight detail very well. For this reason, they are well liked by wedding photographers as well.
Like rueyloon mentioned, a good lab is very important. Most neighbourhood labs produces prints with lousy or even horrible colours.
I've said this many times and I'll say it again: Do your camera and your effort a favour: Go to a good lab, don't cheap out on the processing. After spending all the money on pro lenses, pro bodies, etc, it simply does not make sense to process your film at a lab just so because it charges $0.20 per 4R.
