I don't think that NPC's go above level 19, at least there are no NPC levels above 19 in the files.
max battle size and density I think are basically the same thing, the ammount of NPC's that can and will spawn in a zone. The maximum I've seen without causing problems with video and lag is 32 but that's on a single high end computer. What 32 NPC's would do on a slower computer and online multiplayer might cause problems for some players.
