Yellow filter

You can leave the yellow filter on for black and white, but it will limit your abilities. Sometimes you may not want the filter effects for a particular shot and other times you might want the stronger effects of an orange or red filter, or even the different effects of a green or polarizing filter. Also, a great many of these effects can be replicated in post processing. I would recommend a clear UV type filter for lens protection.

Yes, you can do that. But you'll be working with an image that has no color information. It will be greyscale, so there's no ability to impart any color filter effect.
