First and foremost, you have Unfinished Business in your BG2 directory, right? Okay, so your BG1 directory and your EasyTutu folder can rest in peace: we'll be working only with your BG2 directory.
It's an English install, right? If so, I think it's best to go the usual way:

1) download ToBBackup from the first post of this topic;
2) from your BG2 directory, delete Weidu.log, override directory(whole folder), and dialog.tlk. Also delete all your mod files and directories - but only mod files!
3) Unpack dialog.tlk and override directory from your ToBBackup into your BG2 directory;
4) Install mods(carefully, one at a time) and play.
Hope it will help. Yoshimo/Anomen's portraits are in the portrait directory, you can delete them from there later, if you like.
