That's a lot of questions to answer.... as far as i know every decision you make in character creation affects the skills and stats of your character. Farming isn't implemented, but you can always roleplay being a farmer. As for food, eating is not required, but i think foods do (or will) work somewhat like potions, restoring health or affecting the restore rates of stamina and stuff. Alts are allowed, and perhaps even encouraged, and yes, if both of your parents were blacksmiths you would have a higher level of related skills. Clothing isn't really in game yet, but all character models are shown wearing clothes (assuming a loin cloth counts).
