Best partitioning scheme?

[Kent West <kent.west@infotech.acu.edu>]

I just inherited a machine with 4 SCSI drives, 2GB each. It'll be a
Micro$oft-free zone. It'll be an a LAN with several of us technicians (7 or
so) having access to it for storage of files mostly, so I'm thinking of
this for the partitioning scheme.

Drive 1:
  200 MB = /
  1.8 GB  = /usr

Drive 2:
  1.5 GB = /var
   64 MB = swap
   the rest = /tmp

Drive 3 and Drive 4: /home

So here's my two questions: 
  1) Does this sound like a reasonable paritioning scheme (I'm a newbie, so
I really don't know).
  2) How do I spread /home across two drives?

Thanks!
