ok, as far as tv selection goes
if your gonna hang the tv on the wall you have two choices, plasma or LCD
plasma televisions do better in bright rooms because of the way they create the picture, its a direct view technology so you are seeing the light created directly by the television, so while you will get some glare from the screen itself, you still will be able to see the picture like a tube
plasma is only available in 37+ so thats something to consider
plasma also has a higher contrast ratio then LCD on average so u will see deeper blacks and more vivid colors
now some people will say plasma can burn in, and that is correct but every new telecvision has built in anti burn in technology which can be anything from pixel shifting to a full blow static image detector. But with the average panel life being 45K-60K hours you need to really abuse a tv to burn an image in
for LCD, LCD panels have a higher resolution then plasmas so if your gonna sit close to the television most people wont report eyestrain at closer distances due to the resolution and the somewhat softer light coming from the panel
in brightly lit rooms however direct sunlight will cancel out the image on the screen making it impossible to view (ever taken a laptop outside? same thing)
ok… now lets say ur gonna go table top
personally i like samsung DLP for microdisplay technology
DLP has the best contrast ratio, the fastest refresh rates and really accurate colors
LCD projection is ok, but its more of a budget minded product now, and most manufacturers are using it as an entry level product
SXRD or LCOS is also ok, but doesnt offer the same refresh rates or blacks as DLP or the Pixel fill rate (how close the pixels are together, meaning the screen door effect is lessened)
recommended viewing distance for a tv is 2x the size of the tv is the best distannce to sit… so for example a 50" tv u shoudl sit 100" away
