1. What is the name and location of that grub config file?
Depending on whether or not you have an EFI system, it's either
/etc/grub2.cfg or /etc/grub2-efi.cfg. Both symlinks exist but only one
of them should be valid.
2. Is there anything I need to do after editing the file but before
re-booting?
No.
