This movie was great! I've read all the books as well, and they're great too.
Violence - Some vampires tracking down human prey, characters talk of "ripping a character and burning the pieces", a character decapitates a vampire, a character is bitten by a vampire, a character gets a shard of glass stuck in her leg (some blood), etc.
Language - None.
Sex - No nudity/sex but there is an extremely steamy make out scene in a character's bed, a character is viewed in his/her underwear and a t-shirt, some flirting and holding hands.
Role models - Bella is a great role model. She is funny, smart, etc. Edward is extremely polite and is very respectful.
Even my little brother (6) watched this movie and loved it, especially the action scenes!
