If anyone's ever seen 'My Cat From Hell' on Amimal Planet, they'd know very well that there's no need to re-home a 'difficult cat' just because the owners have some learning to do.
The OP has some learning to do and yes, it's irresponsible to get a cat or kitten before you know how to take care of it but there's no need for aggressive or silly 'just re-home it because you're not capable' replies.
OP, just get learning

preferably from a book or website that has good reviews from those who've used it and one which covers cat behaviour as well as general care.
BTW - a cat's food and water shouldn't be in the same room as its litter tray, though I do agree with keeping the kitten limited to 'safe rooms' overnight, until it's a little older and settled in. Cats should have free run of the whole house once their older, though if they prevent you from having a good night's sleep on a regular basis, the bedrooms should be out of bounds.
