You will need evidence that you are in the country where you are applying (if via e-visa). Obviously, photos, passport photo page, etc. just make sure your work letter clearly states you get to work remotely

Yes, for visa applications, they ask you to apply within 3 months of travel, because they are usually swamped. Also, most visas are only good for a short amount of time. However, once you have the visa, you can enter anytime within the 5 years (unless they change laws)
