If not for the indoor lighting color biases and potential red-eye problem, I'd think the on-board flash would be ok for a little fill and catch light. Should be fine for daytime outdoors use for instance, but of course, that's not your situation.
BTW, RE: custom WB setting, I remember someone mentioning (long ago when I first started) using a slightly blue-ish white card to yield a slightly warmer, more pleasant WB. Personally, I like it slightly warmer in many/most cases myself. It all depends on what you're going for. At the end of the day, photography doesn't need to be just about some strict, accurate view of reality. In fact, it's probably rarely about that at all (even if most people think otherwise)...
