You are missing the lines for the fonts in your font path section, here's what my section looks like:
Code:
Section "Files"
#       FontPath        "unix/:7100"                    # local font server
        # if the local font server has problems, we can fall back on these
#       FontPath        "/usr/lib/X11/fonts/Type1"
#       FontPath        "/usr/lib/X11/fonts/CID"
        FontPath        "/usr/lib/X11/fonts/Speedo"
        FontPath        "/usr/lib/X11/fonts/misc"
#       FontPath        "/usr/lib/X11/fonts/cyrillic"
        FontPath        "/usr/lib/X11/fonts/75dpi"
        FontPath        "/usr/lib/X11/fonts/100dpi"
        FontPath        "/usr/share/fonts/truetype/ttf-bitstream-vera"
        FontPath        "/usr/share/fonts/ttf/western"
        FontPath        "/usr/share/fonts/ttf/decoratives"
        FontPath        "/usr/lib/X11/fonts/Type1"
EndSection
You should be looking for the proper paths in /usr/share/fonts/ttf and truetype and add the paths then re-start the X-server to have them available to be used. You should move the FontPath "/usr/lib/X11/fonts/Type1" to the bottom of the section to have them used as the last fonts in the path and have the true type fonts above them so they are used first. If the fonts look to big and blocky you should move the 75dpi line above the 100dpi one in the XF86Config-4 and check in /etc/kde3/kdm/Xservers and change the -dpi 100 lines to 75 and re-start the X-server.

[edit]
You may want to look at this thread to see the file paths you should be looking for.
