I'm new to playing Survivor, and I spectated Pantheon, and just went "oh wait, this is just being social to people. I already do that. That's easy" and just went from there. I don't really care about sitting at the top if I'm well-liked either, because I don't feel like I'm in immediate danger of being backstabbed and getting booted if I'm well-liked.

As well - I looked it up. It's not Memorial Day, since that's in May. It's Labor Day. I ​always forget Labor Day exists, since I don't really think about it. Labor Day is about the workers, and Memorial Day is about the veterans who gave their life for the country.

Francis was gonna be the first boot if nothing happened. With Royal now here, I'm really not sure. I know the main target was trying to figure out who got all the items and go from there, but I literally just woke up, so I haven't really seen if anyone sent me any further thoughts from there, because I still don't think there was an idol amongst them.

This is a a quality knife.  Looks like it's Khaki Scout branded.

Heist planning notebook
While the notes are a bit juvenile, it looks like they contain a plan to lift an immunity idol from a future challenge.  You just have to put some tape on your nose, then while participating in the upcoming Train Brawl challenge, find time to sneak off and post in your confessional once during each round of the battle.  During the first round, you have to break into where the idol is located.  Post "BREAK IN" into your submission thread.  You need to do this before the round ends, or it'll be too late.  During the second round, you'll need to grab the goods.  Type "GRAB IDOL" in your confessional during round 2.  Finally, during round three you need to get away with the goods.  Type "ESCAPE" into your confessional during round 3.
