Will this grille need paint before installation?

Depends on finish preference. The grille ships ready to bolt on as-is. If you want color-matched finish, sand lightly with 220-grit, apply primer, and paint to match your truck before install.

Do I need new hardware to mount this?

The grille uses your truck's factory mounting points, so fasteners already exist. Verify condition when you remove the old grille—replace any bent or corroded bolts before installing the new one.

Can I revert to the stock grille later?

Yes. This bolts to the same factory points, so swapping back to OEM takes minutes. Keep your original grille if you want that option.
