Hi, Andrew:

Q. "...how should the addresses be set up?"
A. On different networks.

Q. "...Is this wrong?"
A. No if you 'subnet', yes if you do not.

Statement: "But 'workstation1' cannot ping 'fw/server', even after doing
'route add fw/router gw server eth0'."

Comment: I would like to see the output of 'ifconfig' and 'route -n' on
'workstation1'.

You have, at least, one other topology option without adding hardware.
Though,
I'll try to answer your question modified thusly:
"What is ['the correct','a way','a good way'] to address machines in
this sort of topology?".

internet<?>fw/router<192.168.0.1>------<192.168.0.2>server<192.168.1.2>---
---<192.168.1.3>workstation1<192.168.2.3>------<192.168.2.4>workstation2

I think. Your mileage may vary. ;-)
