I'm playing Fallout 2 RPU, and I'm having trouble...

I'm trying to find every new stuff that were "restored" but I'm struggling finding some of them. I want to discover the following:

1. Village outside of Vault City + their experiments
2. Hubologist Stash
   
3. Enclave Vertibird Landing Pad (I assume its different from Navarro?)
   
4. Dr. Sheng and his hideout
   
5. Dialogues about Kaga (I tried returning to Arroyo but their dialogue is about getting the GECK)
   
6. Ian (I haven't seen him)
   
7. Orphan quest (The Den)
   
8. Money Skimming quest (Broken Hills)
   
9. Convincing Shadow Who Walks (Raiders)
   
10. Creating more Heart pills for Cassidy
    
11. Guide for Vault 13 good ending
    
12. Password list in Shi Temple
    

Please be detailed on what I need to do, thanks in advance.
