Honey, go through Rush and see what happens! I think you've managed your own expectations very well and you would never forgive yourself if you didn't rush (well, maybe that's a little strong....but you would wonder "what if?")
And, for the detractors, they've made their points of view known....no point in discussing it with them. The only thing is, make sure that you can take on the financial responsibilities of the sorority (some people need to rely on their parents for this), or can manage it through the payment plans process, etc.
We are all hoping the best for you!
