All three of your questions can be answered at the same time. Every course you have taken for a grade (doesn't matter if it won't transfer to UC) counts. The 2 F's will count for your LSAC gpa and thus will be lower than your school GPA.
I learned that the hard way. I went to school in 2000-2002 while working full time. My last semester I stopped attending classes in October and did not withdrawal. 4 F's tore down my GPA that I built up upon my return to school in 2007
I'm in the same boat, were you admitted to any schools to which you were bellow their 25th percentile gpa? Also, did you write an addendum pointing out what your gpa looks like with those discounted?
