Nerritti: Alright, I'll go ahead and use BGT then. By the way, I threw together a quick list in what I hope is a decent install order (if you have any suggestions as far as changing the order, that would be helpful):  
 Baldur's Gate 
 Baldur's Gate II 
 Gibberlings 3 BG2 Fixpack (Using Linux WeiDU) 
 Baldur's Gate Trilogy 
 BGT Fixpack 
 BG1 GUI 
 Restored Textscreen Music (and English Language Pack) 
 Baldur's Gate Graphics Overhaul 
 BG Mini-Quests and Encounters 
 BG1 Unfinished Business 
 The Lure of the Sirine's Call 
 Sword Coast Stratagems 
 BG1 NPC Project 
  I usually only install the fixpack and tweakpack, so am not sure when it's best to install what, but I'm sure you can find that in mod guides, perhaps the one here on GOG too. I see one potential issue though. At least with easyTutu, it's recommended to install it when the base installs are clean, ie before any mods. Not sure if this applies to BGT too, but I would assume so, in which case you could install the Fixpack after BGT. See there are two fixpacks there though, so maybe you are well on top of this, just thought I'd point that out. I made that mistake on my own install, so BG1 got messed up.  
 Good luck. I hope you get it working :)
