NEW to GTA5 mods. A noob looking for any help

[HFDFirewood]

As stated, im new to the website...and to modding in general.
So, to make this fast...a quick question to determine if i can mod what i have and do i have the necessary skills to pull it off.
Here goes...
First...im a 45 yr old from Nova Scotia Canada. And have never modded before. Ive seen alot of videos of mods....and looks awesome. Just looking to make this 7 year old game a little more fun

I have a downloaded copy of GTA5 on a slim(not super slim) stock PS3.
Have PC and USB stick

Are there any options for modding?

Any help is greatly appreciated
Thanks in advance

@HFDFirewood You'll need to buy it for PC, no console modding or support here. Not even discussed here.
