Honestly, yeah -6 is waaay much. However I always found when reading books about drow, that it was the SR and their magical aptitude (+2 saves, +2 int an all that) that made them really deadly and very interesting. If you're not going to place an ELC on em, I'd remove everything but the SR and Intelligence. But that's just me. ZV-
 Oh yeah, I posted a link to the NWN Vault around a week ago. Think it's in the World Suggestions/Comments/Ideas section. Has subrace skins for pretty much every subrace there is, and it's pretty close to what Layo has with ELCs and everything.
Edit: Here it is.
