Extra Red Orbs

When fighting those sword-wielding Olympian skeletons, kill some so that there about ten left and position Kratos with his back to to a wall. Equip the Claws of Hades (which need to be at level 2 or higher). Repeatedly lash out with the Soul Rip (L1 + CIRCLE) and you'll get hundreds, even over a thousand hits on just a few enemies. The Soul Rip attack deals very little damage. On hard modes you can probably increase the hit count further and be rewarded with more red orbs. Note: If you don't back against a wall you'll have to move towards enemies a bit after each attack.

Unlimited Red Orbs

Instead of meeting Aphrodita in a chamber in the Upper Gardens area, go there without talking to her and open the two Red Orb chests. Collect them, then return outside and get past the moving platform and mechanism that is next to the ledge. Return to Aphrodita's chamber and you can open the Red Orb chests again. Do not talk to her, and repeat the process as many times as desired.

Weapon Carry Over Exploit

There is a glitch where you can carry over your weapons and stuff to a new game. Note that this is an exploit, and may be patched with future updates to your Playstation 3...

You need to pass Challenge of Olympus first.

Open up Combat Arena and set up the game as such:

Health: Unlimited.
Magic: Unlimited.
Item meter: Unlimited.
Difficulty: Titan.
Other settings will not figure into this exploit.

Enemy 1: Gorgon Serpent (set to count 3 with attack and respawn on).
Enemy 2: Gorgon (set to count 3 with attack and respawn on).
Start the match. Proceed to die five times by jumping in the air as the Gorgons freeze you causing Kratos to shatter (and die as a statue) as he hits the ground. Once you have done this, you will be asked if you want to switch to Easy Difficulty. Select "No" and upon choosing this, you will be taken back to the main menu.

Choose 'New Game' at whatever difficulty you like and you will now have all the weapons, unlimited health and a good chance to break the game by breaking things before you normally would(i.e Smashing the onix on the back of the Three Judges heads).
