Should be fine with just the Russian international passport and the green card. Make sure you are ok with the expiration of the documents. Russian international passports generally expire in just five years from the date of issue. US passports and green cards are usually good for ten years.
Also, as far as I know, you will also need to provide exact matching spelling of her name when booking the airline tickets.
