We are missing some pretty basic information, like, where do you live? What is your budget? How large is your room volume and is it open to other rooms or closed off? Is this for both music and movies, or more for movies? How loudly do you listen to music/movies? What are your expectations?
As far as budgeting is concerned, a good rule of thumb is to spend no more than 25% of your budget on the AVR and probably less. Most of your budget should be spent on the main speakers (or front stage) and the subwoofer (the subwoofer will often cost more than your front stage). And in general, you will get far better components if you buy them separately and not in an HTIB configuration.
