BGT is a mod that allows you to play Baldur's Gate, Tales of the Sword Coast, Shadows of Amn, and Throne of Bhaal as one game. When you finish Baldur's Gate (ie, when you defeat Sarevok) you move on to SoA with all your party as you last had them, two will die if they are still alive and the rest will either come with you or you meet them in Amn. You can download the mod here. BGT-WeiDU is currently available, and is strongly recommended to anyone wishing to play BGT.
BP-BGT is a different mod. With BP-BGT you got BGT with all the added stuff from BP. BP-BGT made BG1 a whole new game with Horred's great enemy AI, added mods like BoneHill, DSotSC, and NTotSC and fully functional BG2 and TDD spells. Download here for the files that you need to make BGT work with BP.
The recently released BP-weidu has made obsolete the old BP-BGT - now, if you wish to use Horred's improved AI, you no longer need to install TDD, SoS, or TS. you still can install these, and other large mods - CtB, DSotSC, NTotSC, BoneHill, NEJ2, however, along with yr BP install (or yr BGT install). BP-BGT now refers to whichever combination of these mods - the BP family - that you choose to install.
