Type looks terrible in IE6, 7 & 8 (using the Lightfantastic theme)- Does anyone have any experience in fixing this?

The type looks terrible in Internet Exployer (vers 6, 7, and 8) and I don't know what to do to fix this. I am a newbie at this and need some guidance from someone here.

I did go to http://drupal.org/project/conditional_styles and did the following but it didn't work (see below. What can I do to get this type to show up properly? Please help- I don't know what to do here?

1. I have already gotten the conditional_stylesheet module and put it in and turned it on.
2. I have already put this code in the .info file that resides in that theme folder (Lightfantastic.info)(see code below--but does it work for IE 6, 7, &8?):
; Set the conditional stylesheets that are processed by IE.
conditional-stylesheets[if lt IE 7][all][] = ie6-and-below.css
conditional-stylesheets[if IE 7][all][] = ie7.css

I Don't know what else I need to do. Can anyone please advise me? And if I need to write 2 more css files as it says above What do I put in them? and where do I put them after they are done??
I am at a total loss here.
Nothing is working to make the type presentable In the IE6, IE7, or IE8 browsers.
Anybody have any suggestions for me?
Thank you so much whoever is out there who knows! Please let me know what to do.
