Questions For Those Who Have Physically Seen Hamilton, From Someone Who Only Listened to the Album

Hamilton is coming to my neck of the woods (Chicago) 😃! Tickets are muy expensive 😫. It does not look like I will see it live in my lifetime. So some questions about things one can't glean off the cast recording alone...
  1. What is Peggy Schuyler's schtick?
    Is she played as a younger immature sister, or more like A Lady Edith type that everyone hates?
  2. Does Hamilton's apparel become progressively flamboyant as he prospers?
    Jefferson seems to disparage his clothing a lot
  3. Are there microphones at the cabinet battles?
    Anachronistic, but good for dropping
  4. How does a grown man portray a 9 year-old Philip?
    He sounds cute when he rhymes, but still super old
