So I found almost all of the landmarks except the Kini Nui pathway and Midak's lab. Oh well! Still had a blast playing on this server and discovering all of the Easter eggs, even if I didn't screenshot them properly. It was great to see the fruits of TTV's labor and I can't wait for another opportunity to do this again (survival/Koro-based factions?).
Special thanks to @Poto_The_Potato, @Nidiki, @SpaceCalamari, and @Mesonak for helping me find everything, and thanks to @Eljay for being a gracious host.
