1)Ross has rolling admissions. They fill. Applying now for September is good. Do it now, or you'll be rolled to January.
2) Depends on you. It IS a third world country. Your milk will come from a box, or for some brave souls, powder. They will run out of eggs. It does rain 350 days of the year there. Their electricity is not reliable (scheduled blackouts to conserve...only the schedule is up to them and totally random). There are only out-doorsy things to do (hiking/scuba/horses/ATVing/whale watching)--no movies theatre (except bootleg campus ones), no malls. Letters take 2 weeks to recieve, packages 6 weeks (express=2weeks). Strangers will beg for money every day. If you dont care about such things, then you'll be fine. As far as education, you'll get it. Cable (HBO/CINEMAX/Showtime included...no Fox though when I was there) and internet (cable at dorms, dsl everywhere else) is readily avail. You don't need a car, but can buy one cheap there if you really need one.
3) You might as well apply. What do you have to lose? If you are worried about the $100 admission fee or whatever, then you have to reeval your priorities. You have a chance. Have a good explaination for your interview, but don't dwell in your personal statement about GPA.
