Yes. You need to have your signaling _exact_ when dealing with LCDs.
Some are very good at taking the timings of VESA standards. But some support some eccentric Windows timings that are _not_ the exact same as VESA. Or maybe you have configured your monitor for X with bandwidths that exceed the typical VESA modelines.
E.g., did you upgrade from a CRT and just leave your X configuration intact? If so, then you might be sending 70, 72, 75 or 85Hz modes for 1024x768. And even though your LCD might support that analog signaling, it's not as ideal as using the VESA standard modes (typically 60Hz for 1024x768 on a LCD).
You need to open up your LCD user's manual, find the resolution you want, and input the _exact_ 1) Bandwidth 2) Horizonal Sync and 3) Vertical Sync for that mode into a modeline calculator. Then put those modelines into your XF86Config/xorg.conf.
Otherwise, at 1024x768, you're going to see a lot of the distortions. It has nothing to do with fonts.
Ideally you should be using DVI and not an analog connector. That removes the problem entirely.

I don't know where to make the adjustments you've suggested- I've posted my monitor's specs and my xorg.conf below, any help is greatly appreciated.
Thanks!!

Silly question: Does the monitor look good when hooked up to a different computer? (or did I miss that?) What about a different monitor on this machine?

Yes, looks great when hooked up to another machine. I don't have another LCD so its tough to test seperate monitors.

I'm like you in that if I had your problem I don't know if I could effectively solve this problem. From your monitor's specs everything looks good to me but I have one question. From your specs I don't know if your DisplaySize of 300 230 is correct.
I used the following command:
$ xdpyinfo | grep dimensions dimensions: 1024x768 pixels (361x271 millimeters)
My DisplaySize is 360 270. I calculate that the 360mm is about 14.1" and the 270mm is about 10.6". The viewing dimensions of my monitor is close to 14.1"x10.6". If I'm correct then your monitor's viewing dimensions should be about 11.8"x9.1" if the DisplaySize 300 230 is correct. I converted to inches by multiplying by 0.03937. Someone else would have to tell you how to make changes if that's necessary. I'm sure some expert will correct me if this is wrong!
Try the following command: $ xdpyinfo -ext all
