1. No, but you can always make a command that has commands listed in them for each group of users.
2. No, the only two options are in the Config Tab > Master Settings > Misc Settings:
The first option makes it so they don't get deepbot mod if they are a twitch channel mod. So allows you to decide who gets permission to Deepbot Mod commands/permissions.
The second option stops them from adding/editing channel commands.
