Has anyone done testing to see how much memory is actually needed for Unimus?

Is there a standard memory tuning settings that could be done to optimize it's use?

Currently I see Unimus has a java.exe that's using over 1.7GB of RAM

This seems applicable, but since I'm not a coder maybe some default vaules/recommendations might be good?

Here is a detailed discussion of memory usage:

Hopefully that will shed more light on how mem. consumption works, and how to adjust it.

As for recommendations, here is our resource sizing article on the wiki :)
(you can use the values there as the -Xmx argument for the JVM)
