Sergio, thanks for your questions. All info is available at our forum boards for the last 13 years:

Mod site
It's a very long mod which incorporates all the IWD game inside, but only technically. The plot is different. The IWD is split between the first and third parts of the mod. The second part of the mod takes place in a completely different environment, in the Academy of Halruaa. There are several new joinable NPCs with their stories, quests, banters. In the second part of the mod (if you don't install BGT), there will be several BG1 areas on the map available for re-visiting and initiating or completing the quests of the new NPCs. There are also several new areas made from scratch by Gorion for the NPCs quests.
Regarding Tortured Souls, please see the corresponding forum boards. The link to the mod site is above. It is now part of the compilation.
Keldorn's Romance is a new mod written by Senka. One of the best mods, in my opinion, with a lot of material, very well-written plot, quests, new areas, banters etc. There will be a completely new chapter of the war with Riatavin.
Hopefully, the above answers your questions, but please ask if you need additional clarifications. I'm not writing a walkthrough, but I'd be happy if someone would write it for the entirely new adventure.
