Coming from a fan of B&W speakers, I recommend checking out Ascend's lineup if you are ok with bookshelves. I still haven't heard the new 68 series, but I listened to 600s, 700s, 800s... I think they all offer a fair value, IMO.
As for the TV, especially since you are in basement, Id give front projection a look-see. BMXTRIX gave a Mitsubishi rec for about the $1.5k mark or so, and even with cost of screen, I presume the cost is comparable to nice plasmas. Of course, the sky is the limit with projectors, and I think once you get around $2.5k you start to some very nice 1080p units indeed.
