and actually, if you are doing quotas by name ( can you do them by uid?) then the filer would also need to have access to the passwd file.

I believe you can specify a uid in the quota file.
You can specify a file name or directory name in a quota entry and the quota is applied to the owner of that file or directory. The same is true for group quotas. So again, in a NFS only environment you don't need a user database. Here's a typical entry from our quota file:
/h1/s/sc/scl user 100M 100K
