Hello folks - First a big thank you since this forum has been tremendously helpful in my recent audio upgrades. Now I come to you for more help, this time with speakers...this gets a little complicated so I'll try provide as much info as I can - bearing in mind that I've no idea what any of it means ;-)
I recently upgraded my Receiver (actually I upgraded the DVD player, which I somehow managed to convince myself necessitated a new receiver.....aint logic wonderful?)
Current audio setup:
Receiver: Yamaha RX - V663
DVD player: Panasonic BD30K
Speakers: 7.1 arrangement
The tale of woe....(grab some pop corn, this might take a while)
When I got my first surround sound system, I barely had two quarters to bang together in one pocket. So I went with the "Home Theater in a Box" solution. It cost me $400. It was good, very good actually for the money, I thought anyway. This is it:

About a year after I got the system I decided I wanted some different speakers. I bought new rear and front speakers, retaining the original center speaker and Subwoofer. Lets fast forward about 8 years.....
Now older and a little more flush with cash, I manage to convince my wife that "really honey, we need blu-ray". In some amazing feat of marital acrobatics I also convince her that an HDMI-capable receiver is the way to go. I acquire the above listed components, hook everything up and decide that its pretty darned good.....except I'm still using the same speakers. Logic tells me my "theater in a box" speakers from 8 years ago probably aren't doing my new receiver justice and so I'd appreciate some advice on changes, brands, etc
Here are how things look now. I've provided specs where possible and links to the product for your reference.

Ok - thanks for reading this far!....
I would very much like to not replace the Sony speakers - aside from the fact they appear to work well, I really would rather sleep in my bed than on the couch

. SO, I was thinking that I would move the SONY bookshelf speakers to the rear-most channel - making the matching SONY speakers cover all the rear channels, then replace the center and front speakers with something else - question is ...what?
Budget: Don't make me cry. I'm not looking for the top of the line and all I ever do is watch movies with this system - no music or such. Still, I want to make sure my speakers do a pretty good job for the new Yamaha receiver.
Thoughts? Opinions? I appreciate your time and help!.
Thanks,
Allan (Treozen).
