I'm no expert but I'd guess with a 3.2/174 you'll be a very strong candidate for Boalt, and have some chance at Stanford.  Those softs should help you be able to write a killer PS, and include an addendum about your GPA.  You might have a better chance at Harvard than Stanford if the East Coast interests you at all.
