All great questions. The problems with the SF match app are numerous, but the bottom line is you have to work around them. There is no set format.
For the biographical page, keep it short and sweet. Less is always more when you are considering your audience. They have many many apps to read and very little time. If it prints out and looks ok then it will appear ok to your interviewer.
For the public service and research make it a CV format with short simple descriptions and clear dates. It may be understandable to you, but make sure whatever you put is clear to someone who doesn't know you. I.e., if you were president of the ophthalmic waste disposal committee and that was a big deal for you, that has to be clear.
Honors awards and achievements - You can put anything you want in this sections. If honoring medicine and surgery was followed with a certificate of your awesomeness put that in. If you received any grants or research scholarships put those in. If you voluntereed in Afghanistan and made it back alive put that in.
The nice thing about the SF match is it allows (gasp) some creativity on your part. You can mold it to fit your profile. There is no set-in-stone method, so make sure you show the final product to a bunch of people. If it makes sense to people who don't know you well then it should make sense to the interviewers. Good luck
