As long as you run your own server, you can create spawns, permanent spawns, create items and modify existing ones, in fact, you can almost modify everything. Try this with EqAdmin... consult the readme for how to install the software and the databases.
for AA points, they arent working yet...
for the level limitations, well i dont know, i guess that you could if you modify the source code, developpers might answer you better that i do i think
anyway, you'll need to spend a few hours to understand how everything works, read the tutorials and search in the forum each time you need something, and you'll find lots of usefull tips on how customizing your own world !
