HI- :)
I'm just a bit more then a month or so back online after a melt down.
So I'm still in the process of rebuilding my runtimes, (40 gigs+).

Now I's setting up almostly exactly like you described. But I add one thing.
Useing the nameing conventions on the folders I prefix all the names with a simple code. 
Tis been easy for me to remember.

Sort by character base. Say V3. 
V3-folder name------just for V3 character
V3-c-folder name----Just for clothing
V3-p-folder name----just for poses
V3-h-folder name

Match the prefix's in character, props, and pose folders- plus check for name consistancy.

By useing a prefix it keeps ALL the simular item together. So like the Character folder, which can have hair, figures, props all mixed together- When I see the list all of the clothing folders are clusterd-ect....ect...

I unzip to a dummy folder first, of course and manually sort.

It's a massive job- but worth it
Hyper organized is the goal, lol, even if it is impossible.
There is nothing ya can't do the second time around better :)
