Chao makes a great mush. He's basically the bad cop on the ship. He is the head of security after all. Almost all his skills are PVP. Despite this, he's supposed to more of a political character. He goes around the ship easily. People are scared of him because of his skillset and reputation as a psychopath on most ships.
Anyways, I have no idea about 90% of the game, but I'm Jin Su.
"Oh, you're new? Here, take the Commander post."
PS: Any tips/tricks appreciated
I got Jin Su on my first ship. It's not so bad. But you have to be on almost every cycle or an active ship will mutiny on you. Ironically, you took one of the top roles which needs the most socializing (others are maybe Eleesha, Chun, and Chao). Good luck

First thing to know is that you're the big boss. You have missions. You spend one AP to give someone 3 APs. In the first few days, this is usually best used on Paola to get her to do communications. Second best is Frieda to make sure she scans for planets. And then you'll know what to do by Day 3. If the ship has problems with Hunters, give the pilot a mission. If the ship has broken things, give the ship technician a mission. Try not to waste missions on inactives; you don't get the AP back.
You're the only one who can drive the ship too. This makes Jin Su very very very important and powerful. Sometimes you'll have to jump the ship. If you want to move the ship say 4 steps east, you are the one who sets the ship heading to east. Tell someone to put 4 fuel in the tank. You'll have to get the ship (usually just Frieda) to scan for planets first before knowing where to go.
Your second role is to boost morale. You and Janice are the only ones who can directly improve everyone's morale. Give speeches early, usually Day 1 when everyone settles in the dorms or some other crowded area. Later on, you'll be too busy with expeditions and ship guiding to be giving speeches.
Oh and be careful to sleep in rooms with cameras. Jin Su is a favorite target for mush because of his status and ability to control the ship.
When I'm Jin Su I immediately take possession of the anti-grav scooter and patrol the ship. Make sure every things ok. Help fix things here and there. Track suspicious Mush movements. Help research in the Nexus. Take a patrol ship and shoot down hunters (I take Pilot over Speeches).
Actually I strongly disagree with you here. Eleesha and Chao are supposed to patrol the ship on antigrav scooter and make sure things are ok. Chao's second in command for that reason. Eleesha has the Tracker skill.
Jin Su often needs as much AP as he can get early on. If Janice is inactive, he's responsible for keeping morale up and this requires 2 AP per try. Giving out missions costs a little morale. I'm reluctant to get Pilot for Jin Su because of this... the first skill is the most suitable for him. Pilot is just there because Jin Su is expected to lead expeditions... everyone is usually afraid that a mush Jin Su will steal the ship while everyone is in Icarus.
He is the guy who has to boss around the rest of the ship and know what everyone's up to though. He's like a CEO. He does little of the low level work and more bossing around people.
