are now my "NDMP" media servers. The backups would go across a dedicated GB
network.

Yes.
A 3-way backup is automatic when you refer to a storage unit on a
different NDMP host than the data host.

space needs, etc? What is the minimum filer I could use as these media servers
-- little 720's with one shelf/minimal disk? or would this require a beefier
filer?
There isn't any disk space impact on the tape agent host (at least as
far as I am aware). The NDMP server is just moving data from the
network to the tape drive.
Someone from NetApp would be a better source for what CPU resources
would be needed.
Note that even if NetBackup supported backup to NBU media servers you
would still have the impact - its just moved from a filer to the NetBackup
media server.
