You have concentrated on a couple of factors here — the display frequency and the native screen resolution — but other important considerations include the size of the screen, contrast ratio, colour accuracy and what you intend to watch.
So, what matters most?
Let’s look at effect of screen size. At 32″ there is no advantage to 1080p (there is no TV at 1080p, so unless you intend to watch HD DVD or Blue-ray at a distance of about 4 ft (more and you won’t get full benefit and might as well buy 720p).
At a typical viewing distance of 8-10 ft a person with normal eyesight would need at least a 60″ HDTV to be able to see the difference between a 1080p and 720p HDTV.
Refresh rate? Reports I have read say that in most cases viewers can’t tell the difference between 60 Hz and higher and even then only on large screens … so 100 Hz is basically a waste of money at 32″. 120Hz is a multiple of 24 which can provide some benefit in reduced judder if the TV accepted a 1080p/24fps signal (only applicable to HD DVD or Blu-ray) … although note that some reviewers find that the smooth motion is unnatural so I’d avise you to test before buying to see if it is a benefit in your view).
Programming? HDTV is broadcast at 720p and 1080i depending on the network (I don’t have a number but it isn’t 99:1 it’s much more even than that since the networks are split on which they prefer). It doesn’t really matter since the theoretical differences pretty much work out as a wash in practice, and it wouldn’t matter anyway because you can’t change the network broadcast resolution anyway … you need your HDTV to handle both … and all will.
The only source of consumer 1080p programming is HD DVD or Blu-ray … but at 32″ you would be wasting your money with a 1080p display … you just won’t see any significant difference (except possibly at a very close viewing distance as described above).
Picture quality is determined primarily by contrast ratio, colour saturation, colour accuracy and resolution (in that order), so if you want to get bang for your buck, pick an HDTV with the best contrast ratio you can find (this is basically where plasma TVs beat out LCD … but plasma isn’t a viable option at 32″). But don’t get fooled by numbers (manufacturers can and do inflate figures), look at the picture (in a dim room since ambient light destroys contrast) and go with the model with the most “pop” or semi 3D look.
A further consideration is the video processing … good processing costs money so … my advice is if you want a 32″ HDTV buy 720p and don’t worry about refresh rate (at least don’t pay any extra for it) BUT look for the best contrast ratio and electronics you can get. You might look at the XBR4 model from Sony?

720p without a doubt.
With computers, 1080p is hard to run unless you have top of the line graphics cards. Yes cards, as in two of them.
On TV 99% of the programs run 720p. 1080p is useful for 46” on up.

One it the number of lines or DISPLAYED resolution; 1080 is MUCH better then 720.
The other its the REFRESH rate, or how many times a screen renews itself. A 100 hz refresh rate is far faster theh the human eye can determine. BUT, a 1080 vs720 lines of resolution CAN be seen by some eys as a less then perfect picture.
To me, for my money, I would go with the 1080p and leave the refresh rate for the techies to fight over.

Fel is incorrect….SPORTS use the 720P modes and The REST of the Stations use 1080…..
That’s NOT 99%, Thats 1% use 720
Now, if you game and you NEED fast action, THEN the lower resolution 720P with 100 Hz Refresh rate will deliver a FOCUSED high speed picture…..All you have to do is HOPE Espn has GOOD high speed cameras….
The REST OF THE WORLD couldn’t care less about sports….We like to see everything so super clear and sharp that we NEED 1080 resolution….we want to see it so sharp and detailed that we could REACH IN and Pull Out whatever we wanted to…..
1080 delivers it….AND it delivers the 100 to 120 Hz Refresh rates too…..
So make up your mind, are you Sports Boy, or The Detail MAN ?
