coercion does give you a more refined view on the story and more manipulative approaches, it's not really a requirement but more of an option for role playing perspectives. for reward it can be a trade off between story and xp but it will never have a dramatic impact for the whole of the game.
lock picking is no requirement to play the game, the items you can find in them were deliberately kept limited in use. it does help for exp, gold and traps but you sacrifice something other in stead just by making a choice.
cunning gives a general modifier for many things, though rogues get 2X the benefit for combat skills compared to other classes. unless it's really low you do not really need it for other characters, but just for combat reasons a few points do not hurt one way or another, especially for your main character who'll have to deal with npc's in conversations.
it's an rpg and you can pretty much play it with whatever party you want, though some difficulties will be more suitable than others for different parties and the learning curve is steep. you can adjust your difficulty whenever you like it though and there's no shame asking for help on the forum, you would not be the first who apparently got 'stuck' but managed to get out with some advice. the easiest plays involve a party with a tank (mostly warrior with shield, otherwise shale) and a mage with healing skills. keep some suitable ranged weapons besides your usual weapon and do not just waste your potions because you might still need them for your next fight.
