So after Anor Londo I've just been wandering aimlessly, tying up some loose ends. Finally found Havel and killed him, also managed to get the Drake Sword about 50 hours into my playthrough!
Just now went down into the catacombs then progressed into the
and found a serpent ring that boosts souls, sadly it doesn't really boost that much 
Edit: Tomb of Giants turned into a dead end with another gold doorway, so now I'ma poke around in New Londo and see if I can dig something up.
