Bedroom receiver
I would recommend an entry level Yamaha, Denon, Onkyo, or Pioneer receiver that has the iPod dock you want for $2-300. Spending $1k on a receiver wont improve the sound quality of your satellite speakers. Connect the HDMI video directly from the source to the TV.
Another high WAF speaker option is in-wall speakers. When installed they are flush with the wall and can be painted to match.
