No, you're fine, between dealing with 2 of my own kids and typing this out, it just takes some time to type out.
 
I have also forgotten to mention that you will need to enable tools for ASI plugins. In OpenIV, go to the "tools" tab and open "ASI Manager". Click install on all 3 and click save. 
 
For Resource Adjuster, all files (except the read me) will go into the main game directory. Siren Setting Limit Adjuster is not required and will not function unless you have a car that needs this, but will be installed to the main game directory.
 
For Thero's State Wide Services Pack, as all addon packs, follow;
 
 
As Los Santos Protection Squad is a really old plugin so I cannot guarantee it will work unfortunately, but it it has a readme inside it. Just open the main game directory and drag and drop the "lspdfr" and "plugins" folder from the download into the directory. If it asks you to replace anything, you can safely replace it.
 
As for your vest textures, there are a few that match this title. Unfortunately, I am not familiar with the pathway for male characters to replace a single texture, and the one I found doesn't provide information beyond the texture name. If anyone happens to read this and knows, feel free to let him know as I cannot answer that confidently. 
 
To install EUP and EUP Packs;

You're fine. In the main directory outside of OpenIV, you will see a folder called "update". Click this so it is highlighted. You can click the copy button (indicated in the screenshot below) or click CTRL+C to copy it. Open the mods folder and click the paste button or CTRL+V to paste it.
 
Alternatively you can also right click -> copy and then right click -> paste if you are still confused by any chance.
 
Your UI may appear slightly different depending on if you are using Windows 10 or 11, but it is the same method regardless. Also, mind all the other files/folders here, you will not have all them right now unless you install the same mods.

 

If you are using Native Trainer, I recommend removing it in its entirety. Install Simple Trainer as a replacement as it's much simpler to navigate. It's also much more commonly used. The default for opening this is F3 and F4, but you can change it in the trainerv.ini file located in the main directory.
 
Some housekeeping things to save you time are to install Modified Game Config, HeapAdjuster, and Packfile Limit Adjuster. HeapAdjuster and Packfile Limit Adjuster will go into the main game directory. Your game config will need to be placed in OpenIV. 
 
To do that, open OpenIV and navigate to update -> update.rpf -> common -> data and click the "copy to mods folder" button on the top of your screen (make sure you are in edit mode). Navigate to the same pathway in the mods folder and drag and drop the gameconfig.xml file from your WinRar archive to OpenIV. To know that it was successfully replaced, it will show "compressed" instead of "compressed; encrypted;" as it is your first time installing them.
 
You do not need to load games to make sure that they work as they are prerequisites for the future, but you can if you would like. Also if you would like to, you can go to the main game directory and copy the update folder into the mods folder as it may save you time in the future but also takes up space. That's entirely up to you so you don't need to go copy each pathway each time you want to install something.

i also added you on insta NoKarensWant3d is my name there.
 
All of the above was a success. was able to go on duty and take calls. the native trainer kept getting stuck on screen but just cleared tasks in f4 menu so no big nothing is perfect.

Okay perfect! I finally just deleted and redownloaded the game, OpenIV, and winrar last night when I went to bed si its all a fresh start. lol I will do the above things and come back shortly and again thank you so much for your help!
