Infinite Orbs:
For any Underground Orb mission, if you grab the Orb at exactly 0:00, you'll get a "Mission Failed" and also the 3 Orbs you won. If you choose to try again, you can do this over and over and keep obtaining 3 more Orbs.
Dark Jak vs Final Boss:
After the cutscene before the final battle, hold R1 and you'll transform (or stay as) Dark Jak, regardless of Dark Eco meter.
