Call out changes/subs or wander around tracking people?

Not if you are doing your job and maintaining your line-up card properly.

Unless you have an official scorer(scorekeeper), simply notify a coach of the opposing team. If a coach doesn't have a change which you announced, that is between him/her and whomever they handed the scorebook.
