1000VA would be the minimum with the monitor connected.
The monitor spec should say what the power draw (amps)
is. Then determine the power draw of your workstation.
(a $50 amp meter from a hardware store will measure this).
If you do not wish to purchase the amp meter, just keep 
the packing and return it after use.

Do not plug a printer into the battery protected circuits
on the UPS, just the surge protection. Printers draw heavy
amperage for short durations that can kill a UPS.

Triplite, my brand of choice, should work with NUT. Never set
it up myself.

Make sure the UPS you choose, internally uses the Standard 12VDC-7AH
jell cell battery as they are easy to find and replace and cost
effective. Often, that is all an older UPS needs.

Google for "Sealed Lead acid Battery 12V 7Ah" with F2 connectors
after looking inside at the battery(s) currently in your UPS.

hth,
James
