Need Help Selecting a New TV

Hi Everyone,

I recently remodeled my basement and am looking for a new TV. I haven't shopped for one in 5 years since I bought a Bravia, so I could use some help as I know that the technology has changed so much. I'm very much a noob at this point. If anyone has any articles that they wouldn't mind posting a link to that can get me up to speed, I'm certainly interested in learning more. I just don't have the time to delve into full blown research on this like I used to when I had more time for this hobby.

Price: I'm looking at be in the $1200 or less range preferably.

Size: Likely 46"

Use: I plan on using it for a bunch of things, but probably mostly Sports TV, then movies, then games

Features: I'd like a web enabled TV that can allow me access to some streaming movie companies, none of which I have accounts with at this time. Youtube, Pandora, Skype, Facebook, all pluses. I have no idea if I can break into 3D at this price point. The Samsung Smart hub propaganda looks pretty cool, again, no idea whether $1200 gets me into that.

The TV will have a few very bright LED ceiling lights in front of it, which might be on dimmer, so brightness is kinda important.

Thanks to all who can offer some suggestions!

Danediz,
Awesome, thanks a lot for the options. There are so many models out there. Do most 3D TVs require the glasses? I heard that some don't need them anymore - can that be true?
Is the Sharp Aquos still a quality TV? 5 years ago they seemed #1 or #2 to Sony. I heard that Sharp is hurting financially.
Thanks again!
