Take a look at reviews on the Energy Micro 5.1 speakers. They get very good reviews for small speakers, if small speakers are what you want. There are too many good receivers to suggest only one, but Denon, Yamaha, Onkyo and Pioneer are some of the better brands.
Asking for a recommendation for Reciever+Speakers to connect to my new 55 screen LED. better the smallest speakers as could be- but qualified.
