Apartment Speakers - Denon 1712

Greetings!

I am looking for recommendations for first time speakers purchase for a home theater system. I am/have built an HTPC, and have settled on the Denon 1712 receiver. My TV is a 48 inch Plasma. I plan on using the system for 20% music, 80% TV/Movies. I do not plan on gaming on this system.

My Room is rectangular, 14 1/2 feet X 14 feet with two openings, no solid doors. The couch is 10 Feet Directly across from the TV. I live on the 2nd floor of a 3 story apartment building. Room Layout below.

I don't want to skimp on speakers. But I also am not an audiophile. I'm looking for quality speakers that fit within the price range of what the Denon 1712 can handle. I am looking for floor standing speakers for Left and Right, and a Center channel that I can put on the top shelf of the TV stand which sits 18 inches off the ground, and 11 inches below the TV. I would like to add a Sub as well.

At this point, I don't really care about Rear Left and Right Speakers. I would add them at some point in the future though.

Thanks for any recommendations you might have.

Edit:Price Range: 800-1k$

Jay1 - I had read that a good range is twice what you pay for the receiver. I think the Denon 1712 new was $400, so 800-1k$ for Speakers.

Afrogt - My TV floats above the TV Stand which has two shelves. I would like to put the Center channel Speaker on the top shelf, which is 18 inches off the ground, and 11 inches below the TV. I can also wall mount it above and behind the TV, which would put it at five feet above the floor, and 20 inches behind the TV.

I missed the Deal on the Sub that was recommended by Jay1. However, while reading about that sub, I came across the STF-2 Subwoofer.

How well would this Sub work with the Denon 1712?
