 You need at least 6600 souls for Battle Axe +4. If you miss dupes you can kill the Black Knight for 1800 souls. This can be made easier if you pick up the small 800 soul after the New Londo lift. Even with 3 souls you will need at least one dupe. You can also continue with a Battle Axe +3 for less consistent Iron Golem fight.
 Optimal fight is Running attack, light attack, running attack into stagger. If you don't manage to stagger him you can run behind and stagger with any hit while he's positioned correctly.
 Giant's Halberd is used for the Royal Wood Skip. RWS is really precise with this weapon and gives you midroll. Alternatively instead of killing Andre for the Crest of Artorias, you can buy it from him along with the Bastard Sword. RWS can then be done using this weapon which lets you keep fast roll.
 This is the setup I used to get enough damage for a parry quit out:
Parry and riposte Gwyn's opener. Rotate around him by 135 degrees-ish and attack once.
Parry and riposte again, but then rotate about 90 degrees, backstep, hit then hit again.
Again, parry and riposte and follow up with the 135 rotation and attack.
Finally parry once more and quit out as Gwyn dies.
Alternatively you can ignore the backstep attack and just loop parry, riposte, hit until he's dead.
