There is one more problem I'm encountering as I typset the next book for our publishing house. Within my main body text paragraph style, I have been using two very helpful GREP stylings which automatically add a bit of space around em dashes and ellipses (by increasing the tracking space). But then, when I select an entire paragraph and manually change the tracking (as I work to prevent widows and orphans) the space around those em dashes and ellipses then gets overwritten. Does anyone have any suggestion on how better to do this so that the tracking space around these characters stays put? I've attached a snapshot of the GREP styles I'm using.
