Check avsforum.com. The forum posters know a lot of the issues between models; each brand has their quirks. There are also calculators for screen size versus viewing distance on various sites. Last year I purchase a 58" Samsung 6500 plasma. From 17' that size is good but could have done 63". Generally I think it is better to error on the larger size. Mounting height imo, should have the center of the television at the level of one's eyes or so. People who wall mount always do it too high. I don't know why they want to look up all the time.
It is best to look at the different types of televisions (LCD, LED, plasma, even rear projection) to see which looks best to you, and that will narrow the pack. Each has its advantages and disadvantages, but all types have improved to mitigate their respective drawbacks. Internet features are more standard these days, so I don't think that is going to be an issue. Good luck.
