I am a bit hesitant to use "Disgaea 1" to refer to D1 on things visible to normal readers, like categories, but the alternative would be writing out the series wide stuff as "Disgaea series" for everything, and even then, folks might see "Category:Disgaea Characters" and put just any character in that category, which is a no no. So yeah, Disgaea 1 will do. (and I use D1 as opposed to DHOD, so there is your answer to that)

Terms under Gameplay, and subcatg and reclass them just Terms. So yes to both.
