hey bailey, i actually saved many miles on my G since i was on a long vacation for the summer and then got myself a Fx35 as a DD so i am STILL around 52k

and the belt seems fine for now for another few thousand miles but each car has different life spans on the belts depending on many factors
Otherwise our cars have a timing chain so you dont have to worry about changing that for atleast 100k and i have checked the belt a few times and if i remember right then I am 99.9% sure our cars just have one serpentine/drive belt and thats all you have to change and should be pretty easy with a diagram but make sure you ask someone on this forum who has already done this.
Hope this helps
