tscuz, all of those links are absolute garbage.
1. Those are all mods.
2. They're outdated
3. Most of them are from unnoficial sources.
We need
plugins. 99% of legit plugins can be found at
http://dev.bukkit.org/ . They have to be made for this version of Minecraft, 1.4.5 (however, most 1.4.2 plugins are compatible.)
As for the idea in general...it'd probably be in our best interest to get the Towny map back. Seeing as the temp map died off and has been up for a month now i'm certain that nobody would be interested in such a map.
