I don't really have any advice either.
But I don't imagine that my name change will be legal for quite a while - I'd like to change it before the end of next year, but we'll see.
So for now, I use my chosen name whenever I can; in public, with friends, with family, on the phone, at school (At the beginning of every semester, I go to my teachers and tell them that I hate my given name and go by something else, They are always very accomodating, probably because my birth name is atrocious and embarrassing xD) At work, I still go by my birth-name, but I plan on changing my name-tag soon, because I keep getting called a 'young man,' by the customers and it's starting to cause confusion between my co-workers (The customers will refer to me as the 'young man' at the registers, and my co-workers look over and see me...who they think of as a female,) It's actually quite funny if you ask me. Wow, this is turning into a rant.
But yeah, I think that's about all we can do, is to just use our chosen names where the legal issues won't get involved or cause troubles.
