I second the Gallo speaker recommendation (www.roundsound.com). Although you may be better off with a non-Gallo subwoofer. The speakers have amazing sound, small package, versatile mounting options and aesthetically will complement your LCD TV quite well. They'll also be excellent for music.
As for a receiver it has been a while, but in the past I've liked Marantz and Rotel. Cnet has some good reviews on A/V receivers.
