The Urn of Gaia
The Urn of Gaia is located on the Colossus level right before you see the Colossus' eye through the window. The Urn of Gaia is at the 1st block moving puzzle where there are a series of rooms and metal doors you need to open. First you have to destroy the statue on top of the moving block. Then when you get into the next room where there are doors on all sides of you, go into the room on your right while pushing the block. Push it all the way down the hall and then jump on top of it to access 2 blood chests and the urn of gaia.

Amulet of the Fates / Outer Garden Battle
Here is a trick to evade damage while dealing it in the Outer Gardens battle!
When you reach the scene with the Fate Statue and behead it, in the Outer Gardens several wraiths and bats will attack.
Bypass all of them without attacking, evade damage, and with a powerful combo (or Rage enabled) smash them AND the statue head blocking the exit. The head will disappear leaving your path free and the enemies cannot follow Kratos.

If you have received damaged while escaping, just heal with the chest on the other side. If you don't want to continue fighting then just leave them behind. If you still want blood and gore, return to the "bridge" side of the door. Cross into the actual Gardens room and you're free game, so be aware. Make powerful short-range attacks and most of the enemies won't get any hits through to you.

*** A wraith may attempt it's underground attack from the other side of the door, but you can still evade it and it will return to the other side of the doorway while you remain safe.

(You can also grab it when it comes out of that attack and beat it silly before sending it back through the door to the garden.)

The Urn of Olympus
After you obtain the Spear of Destiny, grab the Statue of Fate (time slowing); and push it down the stairs. From there, push it to the edge of the water from the pathway you came. After you've done that, get to the other side of the path by running and swimming through the water.
Once you are on the other side, slow time (L1 + R1), but make sure you're in a straight line from the statue so you can activate the slowing of the time. Once the time is slowed, hurry up and backtrack to the large button floor, cross the water that is in the way by grappling it using R1.

When you are to the button floor, head through the door and gather your treasures, of that including the Urn of Olympus.
