The rho chi thing is kinda true. After the parties last fall, our Panhellenic rep would come over to give us "the word on the street." Our rho chis would find some way to get in touch with us. It was usually just to say, "Y'all are doing great! The rushees won't stop talking about you!" My future roomie is going to be a rho chi, and we've already made plans for contacting each other during rush!
The rest of the advice is good. It does stink that there is so much politics involved, but there's not a whole lot you can do about it...except use it to your advantage!
