Advice on what A/V receiver and speaker set to buy?

At the moment, I’ve got a PS3, SKY+ HD and my TV is a Sony Bravia KDL-40X2000. I’m looking to get a good A/V receiver that can handle uncompressed 7.1 sound. I just want one HDMI cable going from each box (PS3 and SKY HD)to the receiver and one HDMI cable going into the TV.

With this, I’m looking to get a 7.1 speaker set that can plug into the A/V receiver.

I’m really looking to spend about £600-£800 altogether on the speakers and receiver.

Any advice on the best Receiver/speakers I can get for this price would be great!

As you can probably tell, I’m a bit of a noob to this Home Theatre stuff and I want to be able to dock my iPod with the receiver. I’ve found this Remote Interactive dock thing ( Onkyo DS-A2X Remote Interactive Dock: Amazon.co.uk: Electronics & Photo) and I was wondering if anyone could explain what it does and what it plugs into.

Thanks in advance for any advice on anything here!
