I'm with the rest of the folks -- inwalls/inceilings are going to cost you more (a lot?) for the same performance. I think you'd be fine putting the speakers on the wall by your piano. Elevated so that that they're 2' from the ceiling maybe? Spread out as much as you can. It's not perfect, but audio is typically about making compromises. If you were to buy the speakers from SVS (which I also agree would be a very good route to go), I'd hazard that they could tell you the best place to put the speakers given your room and limitations.

One more thing -- I'm not sure if this is true, but mounting a tv above a fireplace I thought wasn't a good idea, unless you weren't going to be using the fireplace. The heat and smoke will affect the tv's performance. Maybe that's not true, but it's something I've always thought was..
