My G35 Coupe (will post pics soon) came with a sticker on the rear that says, "Infiniti of West Chester" where I purchased it. How can I safely remove this decal without scratching/harming the paint?

 

As long as its a 'sticker' as opposed to an emblem that has location posts

Use 3M Adhesive remover, soak area and try to lift a corner, then with some fishing line pull downwards and it should come off. Don't forget to replace the paints protection, wax / sealant

 

+1 to TOGWT.

I sometimes also use a heat gun.
