Good suggestions above. I also suggest putting your machine in front of a window with a view, if possible. Consider whether you want a pressing station that you have to stand up and walk to, or if you'd rather pivot from your machine. Will you be purchasing any major new pieces? If so, making them match gives the room a more cohesive look. (My pieces are all white.) I use the rating system for my fabric (8,9,or 10 means I really like or love it. Keep only those except for practice pieces for FMQ. They can be ugly or outdated since they'll eventually be trashed). Keep your fabric away from natural light. Consider housing it in dressers if you're the type who is easily overstimulated by a lot of stuff. Can you easily reach the shelves you're planning to use, and can you keep them fairly orderly, or should you consider bookcases? I'm not sure how much space you have, so these suggestions are all just off the top of my head.
