These are all EET mods, which is the Enhanced Edition Trilogy. You need to own the enhanced editions of BG1, BG2, and SoD.
EET patches all 3 games together to try and make a seamless experience. It does change a couple of the rules for bg1 since it's running in BG2's engine (they changed weapon proficiencies, favored enemies, etc.).

Note that there are 2 categories in the list: mods that are compatible before you install EET, and mods that are compatible after you install EET. The list for before is short so I just do EET and pick from the after list.
Easiest way I did this was install EET, then download Project Infinity (you have to allow the app and process in Windows security: it thinks it's a Trojan). Inside Project Infinity are links to download the mods directly from the main websites.
The most time consuming part is putting together the WEIDU log with the mods in order. I had to look at several weidu logs and copy lines and put them before or after other mods based on how others set up their load orders.
Once I got past that part the game loaded up with no problems.
If you want to run someone else's modpack, you can download and use their weidu log, then download all the mods they're using and it should work fine. These two youtive links have weidu logs of their whole install order. I like the second one but you'll have to find the Made in Heaven (cant remember whats in it but i wish i got it) mod and I think Enhanced Extended Encounters (more bounty hunters after you in BG1 plus a few surprise encounters) which are on the PI list.
If you need any more help let me know. The instructions and process is pretty frustrating to decipher, and it took me a Saturday thinking about it and trial and error.
