I should add that Tomcat is running as a Windows service, it isn't started

Then the .bat files are not used.
Call up the tomcat?w.exe program, and edit the settings in the Java tab.

But if I change the settings in catalina.bat to:
Don't make changes to catalina.bat; create a setenv.bat to hold all your
local settings.
set CATALINA_OPTS=%CATALINA_OPTS% -Xms128m -Xmx768m
-XX:MaxPermSize=128m
In Tomcat Manager I see:
Use a real JVM analysis tool (e.g., JConsole, VisualVM), not the manager
webapp.
Free memory: 97.90 MB Total memory: 122.68 MB Max memory: 227.56 MB
Shouldn't total or max memory have a higher reading?
No, since the heap size is sliding around between Xms and Xmx.
You might want to take a look at the papers here:

Especially interesting are the ergonomics and tuning ones.
