0.1mm layer height gives the best quality in a reasonable time.

The UM2Go is the same as all the new UM's, just smaller and without heated bed,
so setting can be used on all UM2, UM Go and Extended. and even on the original UM
The best way to start.....is just to start
, use the sample UM little robot, if you can print that without flaws then you are on your way 
use one of the three standard setting, print and see what happens, if you see problems, post a pic and we can diagnose where problems lie.
and try to get familiar with the Cura advanced settings.
