I don't remember the AMCAS application having a specific question for the personal statement. It might just say something like"this is your opportunity to tell the schools something about yourself". The secondary applications from individual schools might ask a specific question, however. And those questions will vary by school.
About the LOR's, AMCAS does not handle them at all. Either you handle them youself, or you can use a recommendation letter service (I think there are private ones, but most are organized through your school). My school handled my LOR's for me. I had all the letters sent to the advising office, and for a fee, they copied and distributed the letters when I told them to. That way I never saw or even touched any of my letters.
And each school requests different letters, which can be annoying, although most schools request either a "committee letter" from your school's pre-med committee, or three individual letters- usually two from science professors, one from non-science. Some schools also request volunteer/clinical experience letters and/or character reference letters. If you know the schools you will apply to, you could go ahead and contact them to see exactly what letters they request.
Although my school did not have a "committee letter", your school might. I won't discuss those since I don't know much about them.
