You are correct in that I won't maintain the exit flag without ports 80 and 443 open, *and* I lose my eligibility for a free t-shirt, *but* I am not likely to attract attention at my home either. =)
No exit flag means your relay will not be used as an exit, just as a regular relay. You can therefore get rid of all exit rules because they won't make any difference.
