Hello, I am new to all the GTA 5 and LCPDFR. look awesome and cant wait to play it. I am having a hard time getting started with all the downloads and installation (something went wrong) Is there ay support that can walk someone thought trying to fix it and making sure I have the right things that I need?

I'd suggest looking at Albo1125, Jeff Favigano, and StevetheGamer on YT. They have tutorials on how to get everything set up

I learned a lot through Albo's Way videos 1-7 to get started.  Go to youtube and search Albo's way.   I discovered LSPDFR back in March and it was tough to figure it out.  One thing is to make a back up of the game.  Once you have a fresh install and all the updates then copy / paste the game in the Rockstar Folder.  If you have steam version I'm not sure how the file path is.  I have retail version.   That way if you really screw up the game with mods then you have a fresh back up and don't need to reinstall the whole game which could take a couple hours depending on how fast your computer is. 

I have things already installed like the LCPDFR and others things. Do you think it is wise to uninstall everything and restart?
