Creatures & Area

I'm just wondering what area and creature information would be valuable, yet not too time consuming to get? (we can add the harder to attain content at a later point).

For areas, I've been thinking/doing:
1) Type, i.e., outpost, town, explorable area
2) Connecting areas
3) NPCs
4) Quests
5) Official Description

For creatures:
1) Skills
2) Type, i.e. support, combat
3) Location

Any ideas?

For Areas.. perhaps include what the typical composition of enemies within it is (usually there's only little variance to what you'll run into) and a projected level range for that area.

For creatures, perhaps a few notes on their 'behavior'? For example, a Spined Aloe and a Juniper Bark look exactly the same, but behave very differently.. which might not be readily apparent just from looking at a skills list.

Arent the monster names dynamically set? Or is a monster with the same name always with the same skillstats? Or am I just a big newbie :/
