I am a new user to MapPoint, and should clarify the question...is it possible to format the graph/pushpins based on certain criteria?

I am attempting to emphasize important locations based on revenue, market opportunity, etc. Is this possible?...or will I have to "presort" the data in excel and import a multiple data sets into MapPoint?

Are there any good MapPoint books out there?

Lastly, is it possible to change the map itself only to show the locations where a pushpin is? (avoiding the display of unimportant cities)
