Can anyone weigh in on the usual way of filling in the education section?

The parts I'm uncertain about are as follows:
For high schools:
1. Is it acceptable to leave both GPA and Rank blank (Canadian high schools do not report this) or should I just put my average and since it was highest among my graduating class(an award indicating this is on my resume), should I put 1 for rank?
2. Degree = high school diploma yes?
For university:
a. Since I am still in my final year of undergrad, should I indicate a degree name or just leave blank?
b. Same problem with GPA as high school although I could put my LSAC GPA if that make sense
c. For Rank I assume this is for american schools which report such data?
d. Does "Institution name" apply only if your university is not listed? My university is listed, just wondering if I should indicate my faculty (Health Sciences, Business etc) in this area?
Feel free to answer any pieces individually that you might know. I guess I just want to be sure I'm not disadvantaging myself if I ignore these fields.
Thanks!
