The P/F's won't matter. The withdrawals might raise some eyebrows for the reason that you have numerous of them. But really, spend time worrying about your LSAT and that will cure all your concerns.
With your GPA, if you can get a 170, I would say your odds are good for getting into Cornell, Northwestern, Texas and Duke. Does that mean you'll get accepted at all of them for sure? Of course not. But theres a better chance you'll get accepted at any specific one of them than that you'll get rejected, or even waitlisted for that matter.
You'll have an outside shot at schools higher in the rankings, but odds are against it. I would guess you'll prolly get waitlisted by the rest (besides HYS). However, you should definitly take your chances and apply anyway, ya never know!
