I believe not; I believe that all AFS accesses go through the cache even
if the volumes are also located on the same machine.

Yes, it's recommended.  Although we routinely create and use data volumes
up to 2GB and even larger and don't have too many problems.  Mostly it
just shows up in taking a really long time to move volumes when we need
to.

We generally try to keep volume size down in the 500MB range when we can,
and have a maximum of 2GB for data volumes (with a few exceptions) and 1GB
for user home directories.
