well, for the time being: TOCs by Darth333, Canderis, T7nowhere and tk102 from Holowan Labs/Lucasforums (via waybackmachine):
General Tools & Tutorials:
Modelling, Skinning/Texturing:
Modding Tools (T3-M4's Astromech Droid Center)
There's also a TOC in T3-M4's Astromech Droid Center listing all tools: https://web.archive.org/web/20150906172255/http://www.lucasforums.com/showthread.php?t=152392

.2da Tutorials
Scripting Tutorials
That's at least better than navigating Lucasforums' archive by hand (esp. on mobile).
