Are there multiple endings based on what covenant you choose? Or is it just the playthrough that changes a bit?
No. Two endings and you make the choice at the very end. Covenant may affect some story but not significantly. In fact only thing I think that does affect story is the Pendant.
Covenants
There are 9 Covenants throughout Dark Soul's. You must take an oath to join a Covenant. There are rewards set by the Leader of the Covenant for following the guidelines of the Covenant. All Covenants have 4 ranks, 0 to 3+. Some Covenants will reward you with a promotion, but not all do. Covenants affect online interactions.
Leaving a Covenant
If you break rules of a Covenant and "sin" you will be removed from the Covenant and placed in the Book of Guilty. This will open you up to invasions from members of the Blade of the Darkmoon. You can cleanse your "sin" by obtaining absolution. To obtain an absolution you purchase it from NPC located in the Bell Tower where you battled the Belfry Gargoyles. An Absolution costs 2000XSL. So if you SL (Soul Level) is 100 you would need to pay 200,000 souls to receive an absoultion. Talking to Oswald the Pardoner you can receive a Pardon and be removed from your Covenant without accruing any Sin.
9 Covenants
Blade of Darkmoon: This Covenant has a good alignment. You can hunt down and invade players who have unabsolved sins while in this Covenant. You use the Blue Eye Orb to invade players who have Sinned, this will alert them and can be used anywhere. If you have the ring equip'd you can be summoned to invade a Sinned players world w/o alerting them. Souvenir of Reprisa is needed to gain rank and you obtain Souvenir of Reprisa by killing characters from the Book of Guilty. Currently there is only rewards for reaching +1 rank. You will obtain Darkmoon's Light Sword(miracle) and the Darkmoon's Talisman. To join this Covenant, head to the bottomw level of Anor Londo. You can only access Gwyndolin's tomb by killing Gwynevere or wearing the Darkmoon Seance Ring.
Chaos Servent: This Covenant has an Neutral alignment. To join this Covenant you must defeat Queelagg. Proceed past the area where you fought here, and descend the steps to the right of where you ring the bell. There will be a breakable wall. Once broken proceed down the path, do not affect the egg dude. Talk to him and he will grant you access to the bonfire behind him. To the right of the Bonfire will be a lady. Talk to her to join the Covenant. Upon joining you will receive the spell Chaos Great Fireball. You will also start growing eggs out of your head (eventually). The cure for this can be bought from the egg dude located here as well as more spells. You rank up in this Coveneant by offering Humanity. At rank 2+ you will the spell Chaos Firestorm.
Darkwraith: This is a hidden Covenant that has an Evil alignment. Covenant is great for players who love to invade others. You will be given an item that has unlimited uses to invade others as well as Dark Hand, which when use it's Strong attack you can steal humanity from players. To join the Covenant you need to kill the Great Wolf Sif and obtain his ring, Covenant of Artorias which allows access to the Abyss. From here you have two options. You can not talk to Framps at all and obtain the Lordvessel, then speak to Ingrid in New Londo Ruins to receive the key to enter the Abyss. Or you can defeat the 4 kings before obtaining the Lordvessel (if you don't you will not be able to join for the rest of Current playthrough) and kill Ingrid to get the key to enter the Abyss. Entering the Abyss starts the battle with the 4 Kings, after defeating them speak to Kingseeker Framp in Firelink Shrine to join. Upon joining you will receive a Dark Hand. At rank 1+ you will get a Red Eye Orb and at 2+ you will get Dark Sword and Darkwraith Armor Set. You rank this Covenant up by victories when you invade other players.
Forest Hunter: Neutral alignment. You join this Covenant by talking to the cat called Alvina. You will receive the Cat Covenant Ring
which when equipd will allow Alvina to summon you whenever a non-Forest Hunter player enters the first part of the Forest. After 4 kills talk to Alvina to receive a Ring of Fog. Alvina tells you she hates the wolf guarding the giant sword and asks you to kill him. If you don't you will break the Covenant, but be granted the sword. No rewards for ranking this Covenant up.
Gravelord Servant: Evil alignment.
Path of the Dragon: Evil alignment.
Princess' Guard: Good alignment.
Warrior of Sunlight: Neutral alignment.
Way of White: Good alignment.
EDIT: I'll finish the rest later. All this typing has made me want to play.
