Managed to kill lautrec. Actually managed fairly easy with quite a bit of kiting up and down stairs till they were seperated.
Unfortuantly, 5 humanity was not enough.
Lost 2 humanity due to errors when fighting the 2 big halberd guys (such as pulling both without realising :\ ), and the rest on the bosses.
Had knight solaire+ random summoned each time, but on my very last humanity, i had Knight Solaire and a decent caster summoned.
We killed the skinny guy no problem, then was having no problems with the fat guy also. Then the fat guy got a hit on me.
I wasnt right beside him so i didnt bother healing as it should only of been a hit or 2 till hes dead anyway, plus i was still fairly high hp. Then he jumps in the air....
By the time i realised i should of started running it was too late. Just wasnt far enough away. Big aoe attack

He only had litterally 1 or 2 hits left till he was dead.
Dont really know whether i was closer to tears, or to screaming.
Out of humanity, so now i need to try and solo :\
Edit- Having watched a video, it doesnt really look hard to solo, just takes a bit of time. (hopefully)
Why don't you co-op? Put down your sign and get summoned? That's what I do to get humanity back.
As for the throphy, knights honor was definitely the hardest. Not only do you have to get all the boss soul weapons, you also need every black knight weapon, every silver knight weapon, all tail-cut of weapons inclusing seath the scaleless tail and crossbreed priscella and the everlasting dragons tail. You need rare enemy drop weapons such as titanite cath pole, channelers trident, jagged ghost blade, stone giants sword, stone giants shield. You also need loot found all over the place, such as bloodhsield, effigy, sanctus, dragons tooth, dragonslayer's greatbow, velka's rapier, havel's greatshield. You also need to get the dark hand from darkwraith covenant and gravelords blade from the gravelord covenant. And going to ng+ is not enough: you must go to ng++ to be able to obtain sif's soul 3 times in order to make two different weapons and a shield from his soul. (and I didn't mention all the loot/enemy drop weapon etc, but quite many)
What is From Software's take on DLC? Is it likely they will add new areas or items in the future?
Also, if I pick up DS for my (underused) PS3 will the online features still be available or is it too late?
From Software didn't release a DLC for demon's souls and will not do it for dark souls either, because they believe that once a game goes gold it's complete.
