A battery powered UPS is probably the best you can do.  All the rest is 
probably overkill (except a surge protector ahead of the UPS might save
the UPS from damage on a minor hit).

If you think you can save yourself from a direct lightning strike that
occurs within a couple of hundred yards of your location, you are fooling
yourself.  NOTHING will prevent damage in that case except having the
system disconnected from ALL external wiring (grounds included).
Lightening is nasty stuff and doesn't follow any rules.

If you MUST keep working during a nasty lightening storm, have a good backup
and insurance (on both the system and your BODY).
