If you have to check a clock 5 times because you think you read it wrong, this game may not be the best fit for you because it will not hold your hand through every stage of a quest, it expects players to think and remember, explore and solve things on their own.
The game will have a reputation system and a disposition system for NPC's, those aren't going to keep track of specific things like each character's "Faith" or "Contempt", but how each NPC reacts to the player in a general sense, how much they like them, based on the good/evil actions the player has taken in general, and things the player has done to the NPC specifically (for good or bad). Yes, the NPC's will notice if you change from being nice to them to choosing the "huge jerk" conversation options, and their reaction to you will drop. NPC's you aren't talking to in "huge jerk" mode will still treat you the same. If you continue to act like a jerk, their disposition to you will drop. If you start being nice again, it will rise.
The NPC's won't differentiate between the player characters, even if one is a murdering thief and one is a noble paladin - the players will be grouped together in one faction.
This game is not going to have a dialogue system as deep and nuanced as Planescape: Torment. I don't think you'll be able to just say "I renounce everything, join my party!" Why the heck would he believe you? If you want an evil guy to join your party, but he will only do so if you're evil, it's not realistic to just say "I'm evil" - not if you have an established reputation for good.
You want to get the evil guy who wants you to be evil, then you have to actually do evil things, not just say "No really, I'm evil, trust me despite my never doing anything evil before". That village? Sorry, but you have to actually burn it down. Actions, not just words.
