I hate to start the filter debates, but (
you know when they say that....
) in my experience, a filter is likely to supply broken glass which may damage the front element when dropped. And a sturdy lens shade is likely to crumple when dropped, absorbing some impact. So, I am not of the protective filter school. I have found the problems with reflections and other anomalies to be more trouble that it is worth.
Use lens caps on both ends (when removed from camera). Use lens hoods while shooting. Keep the camera is a dry place. Leave a lens on the camera. Only exception might be a long, heavy lens. I'd keep smaller ones on it, but always remove a premium or heavy lens. They might be prone to put pressure on the lens mount depending on how the camera is sitting while not in use. If no lens, use a body cap on the camera. Wherever it is stored should be as dust-free as you can manage. A cabinet, etc.
Change lenses with the camera body opening pointing down so that any dust and dirt stirred up by removing the lens doesn't fall inside.
Most of all, don't store it too much. Get out and use it. Practice everything. Understand all the settings. Learn what you like and don't. Practice getting your images right and learning from the wrong ones. Have fun!!!
