I'm getting the same type of error with the quota2 line now: open(/nfs/rack/u4/quotas) failed: Permission denied
Since the home directory quota worked without the plugin configuration, my guess is that the plugin config is not using rpc. I can't find any way to force it to use rpc. Again, if I make that 'quotas' file world readable (which I believe isn't good practice), dovecot stops complaining.
Dovecot first finds the mountpoint and then gets its filesystem. If it's nfs, it uses rquota, otherwise local quota. You could enable mail_debug=yes and see what mountpoints Dovecot finds and then see if their type is nfs or something else. Also this would make checking the type (correctly) even easier: http://hg.dovecot.org/dovecot-1.2/rev/eaba4cfeaa44
