I don't think there's anything special to consider in the group/name/classification if you stick to the style of the examples. Please let us know if something seems doesn't seem to work.
If a skill is marked as a Special Maneuver, it is assumed that the bonus is used not by rolling the skill but by some other mean (ie. Body Development, Adrenal Defense, etc.) That means it won't show up in the skill list during the adventure.
If a skill is classified as Moving Maneuver, it will be affected by armor penalties and the general movement modification on the basic character info.
If you are preparing the adventure, it might be better to create a normal character using the wizard, level it up without spending DPs, then manually assigning ranks only to the relevant skills.
Adding a special feature for NPCs would just end up being a reduced version of that I guess, but it might be added in the future if there is interest.
Remember that you can always add an NPC on the fly and just indicate hits, defenses, attacks and use it. You can also "copy" an existing character or NPC, so if you need 3 brigands you just add 1, configure it, and then choose to copy when adding a new character to the adventure.
