Few questions about crafting and skills

1) Are the results of crafting completely random, or do they take into account the stats of the item(s) you sacrifice ?
2) Can you reset your skills, and if so; when and how ?
I would hate to start over just because I didn't have the foresight to know how the game works so I chose "inferior" skills.
