I went through the whole game getting all of the gems except I missed the tutorial gem. I couldn't figure out how to replay the tutorial and get the gem so I stupidly restarted my game... Shortly after I learned you could click "Adventurer Training" I am smart!
Card locations:
1. Left of targets head
2. Far left chair
3. Near coconut
4. On limo
5. Behind dumpster on far right
6. Right of the green smoke poster
7. Bottom left of podium
8. Top right of the red propaganda poster
9. Under the KQJ on the right.
Do the mission by going to the trophies and clicking on the cards.
For the finals boss, I recommend putting 5 mods on engine, crit, evade, and accuracy. Put around 7 on regen and shield, and put the rest on Health (was around 35 for me). Use sawmines and scatter missiles as your weapons.
If I could give one tip, it would be to tap shift to flow. If you hold it you will lose all of your flow but if you tap it you get to keep the speed boost while still keeping your flow.
