Try LXDE - it has very good reputation. From Planet Debian:

Another popular one is XFCE (Xubuntu).

> 3.  Run Firefox as a local app

You need more power (CPU and MEM) on your thin clients, I think. P4 + 
1GB is good one for localapps, I think.

> 4.  Get a gigabit switch to replace our 10 year old 100meg switch.

Change this right now ;-)

"If you have more than 20 users, it is recommended to use Gigabit 
Ethernet connected to a gigabit port on a switch for your LTSP servers. 
Although normal usage ranges from 0.5 to 2mbit, clients can peak quite 
high (70mbit), especially when watching multimedia content."

> 5.  Raid or SCSI disks

Maybe, but this is not a real bottleneck, I think.

This is my favorite ;-)

"A Bohr bug or bohrbug (named after the Bohr atom model) is a bug that 
manifests itself consistently under a well-defined (but possibly 
unknown) set of conditions. Thus, in contrast with heisenbugs, a bohrbug 
does not disappear or alter its characteristics when it is researched."
