For that sort of cluster, you would get better advice on the Beowulf
list.

There are parallel utilities around, including one which runs parallel
terminal sessions (I forget the name for the moment).
Our own clustering environment ncludes extensive parallel tools,
for parallel command execution, syncing, shutdown, power control.

To add users, you can use NIS or LDAP.

Having nine machines is a good start, and a good introduction. 
However, if you don;t have some sort of clustering framework then
re-installing, installing more machines and upgrading will be a pain.
