What's a 3D TV without a couple of glasses and close encounters with a green friend?
Samsung 3D Starter Kit with Shrek

If you already have some 3D content and/or had enough of the green guy on 2D, get this instead of the starter kit. These glasses are slightly pricier but they do not need batteries as they come with an USB connector to recharge. So, over time, you will save some green on batteries. And as you know, those button cells can be a pain to replace!:

DVD Player:
There are a couple of options that I recommend. The first one is a Panasonic DMP-BDT210 Integrated-Wi-Fi 3D Blu-ray DVD Player that comes with integrated Skype, integrated WiFi connectivity and access to a ton of streaming content.

My other favorite is LG BD670 3D Wireless Network Blu-ray Disc Player with Smart TV which too comes with integrated WiFi connectivity and access to a ton of streaming content. No skype integration. But if you took my suggestion and bought the 46D8000, you already have integrated Skype on your TV.

Home Theater:
What is all this fancy visual experience without some great sound? With home theater, there are several options available. I like the two that are listed below. Both have great features that will entertain and engage your family with more than just great sound.
First on the list is LG's LG LHB336 1100W 3D Blu-ray Home Theater System with Smart TV provides great sound with wireless connectivity to your home WiFi network to access tons of apps and other streaming content.

The other one that you could look at is also from LG: LG LHB536 1100W 3D Blu-ray Home Theater System with Smart TV Integrated Wi-Fi.
If you are a real movie aficionado who wants great theater like sound without breaking the bank, this is the one for you: Yamaha YHT-895BL Complete 7.1-Channel Home Theater System

To put it all together, you would need a solid surge protector I recommend this APC 11-Outlet 3020J Surge Protector (See all Surge Protectors), HDMI cables like this one: AmazonBasics High-Speed HDMI Cable (6.5 Feet/2.0 Meters) - Supports Ethernet, 3D, and Audio Return [Newest Standard] (See all HDMI Video Cables). You may need at least two (one for the cable box and another one for the DVD. I usually keep one spare so it's not a silly cable that stands between me and my movies!
To enjoy integrated Skype on new Samsung, you could get a New Samsung Skype Smart TV Web Camera Real HD Video Auto Focus Built-In Microphone Swivel Neck.

Warranty for your stuff:
Several types of extended warranties are available through Amazon.com for all of this fancy stuff. Some are provided by manufacturers while others are provided by third party providers like Square Trade and Canopy. While I have not made warranty claims with any of these to recommend one. Please read the reviews and do your own research to buy a warranty plan that best suits your needs.
