So basically what I'm putting this up for is to know all the general requirements to do so I can run lcpdfr. I've done my research and obviously need gta4, and then I've seen to get lcpdfr, els, patch 1.0.7.1 or whatever, training menu, and a script starting with a b , the name slips my mind. Based on my research I think I'm good with these to start. If I'm missing anything or it's easier to functional run this. Please mention it.

Thanks guys

To run LCPDFR, you need a legal, up to date version of GTA IV and these installed:

Nothing more than that is needed to run LCPDFR. You can, of course add the trainer for making playing easier, and ELS for prettier lights on some cars (at the cost of performance and more crashes). 

Cool thanks. So basically other things are just add on content in a sense

Exactly! You do not need them, but they enhance the game :)
