My sister's cat does the same thing. She won't drink out of her bowl unless she's stuck her paw in it first. I have no idea if she's testing it for something or if she's just a weirdo.
Letting you touch her face and paws is good though, that's a sign of a friendly cat. And my cat sleeps in boxes constantly - we have a box with a towel in it that he prefers to any bed in the house.
