No thanks please- it's our duty to try and help fellow beings, especially on forums(but only if we know something correctly imho).
Coming to the replies to your queries-
(1) A friend, with your exact kind of requirements, bought a C530 sometime back as he watches a lot of movies on his computer.
He paid Rs.34,000/- for the C530 then.
He couldn't find the C550 in stock anywhere in Mumbai then and the dealers refused to quote price for the same.
I suggest you check the same with your regular/reputed stores/dealers.
There was some deal via NEXT or some store where they were allowing 0% interest on 6 installments and the final price was 34K all incl i think.
The USB port on the Samsung LCD TV allowed a lot of formats to be played by just plugging in the pendrive, if i remember correctly.
(2) C530 is FullHD- 1920x1080p native.
(Not HD ready or anything else)

(3) I don't think you need to spend on convertor as the basic output will be analog and the IQ will be of analog out only even if you used an HDMI cable.
The LCD TV has a VGA port (D-Sub) too iirc and you can connect your laptop using a normal VGA cable itself.
(you may keep a cable connected to the back of the TV always)
(4) I am not sure of this format.
Will have to check with my friend/s.

Will let you know if one of them is willing and able to try out the same.
