The font issue is not affected by the absence of quartz-wm. Quartz-wm affects the appearance and behavior of windows. Without it, windows do not look like normal Mac windows, they don't interleave with the windows of other applications, and they can't minimize to the Dock.
There's a setting in CrossOver's preferences which controls whether it will ask for the install discs on startup. On the System Integration tab of the preferences dialog, it's the checkbox "Ask for Mac OS X Install Disc at startup if CrossOver needs quartz-wm". Enable that and restart CrossOver.
