You’ve definitely got more than enough to get started. Only thing I would recommend here is read through the adventure if you haven’t already. Also don’t be scared to improvise if the situation calls for you. You decide the rules you want at the table, not the books. As long as you stay consistent feel free to make any ruling you like if it works for your table.
