A:AnswerYes, if you have cable tv. So everything that connects to the digital box, and you will need an HDMI cable. unless you're sing just the channels the tv comes with.
A:AnswerAlthough I can't directly answer, what I can say that mine is in an enclosed cabinet space that was designed for CRT TVs, so it is deep. Nevertheless, I have not experienced any heating issues within this space, so probably could be placed in bookshelves without overheating.
A:AnswerI found a stand at samsclub.com that uses the holes in back for wall mounting to mount the TV on the stand. The stand is adjustable so TV sits higher than it would with legs so you can get a cable box, dvd player or similar under the TV which is helpful for a small stand. Width from leg to leg is only 18 inches so a large TV can sit on a small stand. Found the TV to be very stable. If not member of Sams Club try www.atlantic-inc.com. Cost about $25 and perfect solution.
