If you are using the Pathfinder Community sheet, the Pathfinder Companion Script will handle resource tracking(ammo, spells, uses, etc.), plus condition and buff statuses on linked token's and the sheet, temp hp, statblock importing, auto ability macros, initiative, and MORE. ;-) Lot's of macro examples on the wiki's Pathfinder Community Sheet guide.
https://wiki.roll20.net/Pathfinder_Character_Sheet...If you are using the Official PF Sheet sheet, grab
GroupInitiative for initiative(examples of setup on wiki
https://wiki.roll20.net/Script:Group_Initiative#Co...) and maybe the
ammo script to handle resource tracking(untested with Official sheet...)
Good luck
