TESIVEdit is not for cleaning up the Oblivion and Data folders, it's for low-level editing and cleaning individual plugins (.ESPs). First glance will likely net you the same response as a first-timer in Wrye Bash, "WTF am I supposed to do with this thing?!"
Here's another guide that should help you out with getting your mods cleaned up using TESIVEdit.
(Psst, I'm a contributor on that guide

. I helped with the "to be cleaned" compilation)
In other news, I decided today that I would extend my Visible When Distant graphics to include the Forts and Cities (minus the Imperial City). This, coupled with the Ayleid Ruins and High-res bridges and castles means pretty much every large structure in the game is now visible when distant for me. Bit of performance hit, but nothing too serious.
