package-cleanup has options that may be able to help with this,
specifically --orphans, --problems, and --dupes.  See "man

Yup, just add your new entries to 40_custom and rerun grub2-mkconfig.

You'll need to rewrite them for GRUB2.  Arch Linux has an good

And, the complete syntax for GRUB2 menu entries is listed in their manual:
