..specifically for 46 inch.

I was told 100,000 or more..is this true?

Contrast ratio is the ratio of the brightest white to darkest black. It is not the leading thing to look at when purchasing a tv because most manufacturers don't measure it properly anyway. It is best to look at the tv before purchasing so that you can see what your eyes find acceptable.

For tru HD experience look for the following:

1080i, 1080p, 720p
120hz or 240hz
HDMI input at least one...

Yep. Refresh rate is considerably more important. If you are not getting a screen larger than a 50", you don't "need" to get 1080p (720p screen that is 1080p input compatible will do) if you are in a cost crunch because your eyes can't ascertain pixel differences at screen sizes lower than 50".
