I just read the article over at crave re 240hz LCD tv. Another development this year is led backlighting like the one used by Samsung. What do you think about this new tech, how much better is it than the old ccfl? Is it more imortant than 240hz?

Two benefits.
Less power consumption, great for laptops.
Thinner screen.
That's it.
I assume you are talking about LED backlighting being good in laptops how about lcd tvs?
Let's say they use dynamic contrast (you research as I don't define these terms.) LED response time is some thousand times faster so that's another plus.

of LED back lighting. The new Samsungs are so thin because they are only edge lit. Many others are fully backlit.
Plagiarized:
FocaLight LED backlighting differs from the simple edge LEDs of the past by creating a matrix of hundreds of LED zones, which can be controlled individually to create a far higher dynamic contrast ratio.
Edge lighting will not give anywhere near as uniform a picture as a full back panel of LED's. Also, local dimming is used on the full panels to give much better contrast ratios than was previously possible with LCD TV's. At CES, Dolby was working on something called Dolby Vision that they claim will do for video what Dolby True HD did for video. The algorithms are only to compliment local dimming and will not work with edge lighting.

Even with that limitation the ability to stretch the contrast with this method was a stroke of genius or madness depending on your point of view. Even a badly distributed backlight could on a bad day double the range.
Let's face it. It's a smart cheap trick.

so would you prefer a good ccfl like the samsung b750 or xbr9 instead of a samsung edge lit led?
I didn't want to show any preferences here except to bring up how LED response times are so fast that it could breathe more life into the dynamic contrast "bag of tricks."
CCFL has issues. Mostly what happens in years 4 and beyond as the color shifts towards red. So far I've seen this without fail in aged CCFL displays and you may want to sit back and watch the fireworks as people discover "how much?" to fix that.

I got lost in your discussion. I have been offered these tow 52" models for the same price. I have a bright room. I have Comcast digital with HD. Can you advise which LCD model I should buy? Or maybe a different LCD is better?
Another potential benefit is that LED backlights should give your TV a longer lifespan than the bulb-back lit kind since LEDs use less power and don't burn out as quickly.
