Qualification: This is based upon my personal experience and opinion but not on extensive work experience producing publicly published copy. For many people, it's going to feel/be more natural to write in the second person. Writing in the first person, when you are instructing someone else rather than describing yourself, takes more conscious effort. It's easy to forget and slip tenses. Also, and important, the resulting language/copy often ends up reading "stilted" -- it doesn't seem natural. Unless you have a particular impression in mind, and the skill to pull it off well, I'd consider going with second person. It will probably be quicker to write, and if you really need to switch to first person, you'll have pre-existing copy from which to start. P.S. I also tend to favor leaving such qualifiers off of labels, except when they clearly help distinguish an item.
