1- When you’re in the Undead Parish, you can find this NPC locked up in a prison cell. To find him, you’ll need to go upstairs in the parish to where the pack of Undead and the Channeler are located. After clearing the room of the enemy, look to the right side of the room to find a set of stairs leading further up. Go up those stairs to the next area and then break through the cracked wall there. Once you do, enter the newly opened area and take the stairs to the top to find the jail cell that holds Lautrec. It requires the Mystery Key to open, and that can be found in the Undead Burg on a corpse. Use the key to open the cell and free him. [a 01] If you do not free him, he will find his own way out after you leave the Undead Parish. Either way, he will appear in Firelink Shrine after you beat the Undead Parish Boss thus finishing the area. Once you have finished Undead Parish, go back to Firelink Shrine and you’ll find Lautrec sitting on the ground off to the right and in front of Anastacia’s cave. If you freed him, then talk to him there to get your reward, a Sunlight Medal. Lautrec will stay in Firelink until you enter The Depths. Once you do, he’ll kill Anastacia and then disappear. However, that is not the end. When you come back from The Depths, check Anastacia’s cave to find her dead body and some drop items. Amongst the items is a Black Eye Orb which you can use to find Lautrec again, and reclaim Anastacia’s stolen soul.
2- While Lautrec is in Firelink, you can get some more dialogue out of him, but you’ll have to go through a series of steps, and pay him some souls. Doing this is optional, but it does give you a bit more insight into the character of Petrus of Thorolund. Again, this is entirely optional and doesn’t impact gameplay, but it is interesting and sheds some light on things.
3- When you reach Anor Londo, make your way through the area to the Boss fight with Ornstein and Smough. In the large room just outside the room where that fight takes place, the Black Eye Orb will begin to vibrate. That is your hint on how to find Lautrec. Once you have cleared that room of the enemy so that it is safe, use the Black Eye Orb to invade Lautrec’s realm.
When you do, you’ll face Lautrec and two of his comrades in a fierce battle. All you need do is defeat Lautrec himself to win, but if you kill his Sorcerer comrade there is a chance he will drop a Catalyst weapon. After you have killed Lautrec, return to Firelink Shrine and again visit Anastacia’s cave to return her soul which will bring her back to life and re-enable the Bonfire of Firelink Shrine.

I hadn't seen this before and if it weren't for Andi posting it I'd probably have come upon it when it was part of some wiki or FAQ in another playthrough or something. As it stands, I happened upon it in the wild. So what if he copypasta'd it. I copypasta'd it to a notepad for my /darksouls folder.
I'm assuming the "undead parish boss" is actually the two gargoyles at the bell tower. Is that correct? If I killed them and rang the bell, should Lautrec be back at Firelink? To clarify I DID free him from his cell.
