 You can manage GRASS region settings from QGIS GUI as well.

 It shouldn't mess with region settings if possible. The concept of region
 is a crucial GRASS feature and you need to get familiar with it, as well
 as with other conventions, to use GRASS. Same as with any other software.

 No you don't have to. You just need to read some manuals and tutorials.
 That means learn basics before you start using.
