I think the server needs a personal waypoint mod. I know there is the warp mod, but i would like this because it is easy to add one, and easy to use

Just use ReisMinimap mod. Not only do you get the map, but it lets you mark waypoints anywhere. No need to add more plugins and make more lag when theres no need (I'm looking at you , Mcmmo).

rei also autosaves where you die upon death so its easy to find your loot

AND, using Rei's Minimap is Allowed :3 Its a win, all around.

just in case you still have doubts; (maybe you see using google as a chor =\)

and while your at it, download mcpatcher:

and then you can install a nice little texture pack:
