Every bike from every brand coming off a standard production line can be improved, they are all built to a budget and a certain standard, and not tailored for your specific needs.
Whether you feel these mods are worth it is a subjective judgement which likely depends on your budget, riding style, and what you are used to. If you were happy with a stock Royal Enfield there is a good chance that you will be ecstatic with the performance of the F800GS. If you previously rode a good dirt bike or a KTM 990 you would probably not be happy with the stock suspension or power output.
At the very least put on a good skid plate, crash bars and hand guards, so the bike will be protected when you crash. The rest of the mods are optional if you want to ride faster or just be more comfortable.
