There's a few different kinds of AA you can use. I find KDE pretty good (above a certain point size), and Gnome 2, when used with the right settings for my LCD monitor. Things get nicer when you recompile Freetype2 to enable better hint usage, too but the link given below disputes this.
re your fonts, do you have those fonts still installed? Are you using a font-server or is X reading them direct? Better yet, check this link out: <A HREF="http://home.online.no/~rut-aane/linux.html#rh8up" target="_new">http://home.online.no/
