Looking for a Receiver with "multi-room" capabilities

So I'm moving into a new place soon. This place has wiring for surround sound in the main living room area. It also has built in speakers in a couple of other rooms (the kitchen, office, and deck).

What I am looking for is a device that will do the surround sound for the TV in the main living room, but also - at the same time - can play music in the other rooms. I understand this is called having a second zone. I talked to a professional about this and he wanted to sell me some very expensive equipment - receiver, amp. remotes.

Can someone recommed something inexpensive that will do what I want it to do? Do I actually need a separate amplifier, or can the Receiver do it all itself? For what it's worth, I intend to hook up a big screen (55-60") TV, possibly 3D capable (since most of them seem to be these days) in the living room with a blu ray player as well.

Thank you for your help.

Thank you so much for your reply.

So, when I have those, I hook the main living room speakers up to the Receiver, and hook the Amp up to the "pre-outs" and then hook the other room speakers to the Amp? Does this Amp. have enough hook ups for approximately 8 speakers? (2 on the deck, 2 in the office, 2 in the study, and 2 in the kitchen?)

I don't know anything about "impedance matching" but each room does have a volume control in the wall for that room's speakers.

If you can't tell, I know next to nothing about audio systems. Is it complicated to set up and get working properly?

Thank you again.

Will the AMP 100 amp work correctly with an Onkyo 515 Receiver? Is that a good receiver? It was one that was recommended by the "professional." I also think we actually have a 7.2 system.

I just want to make sure the parts will all be compatible.
