There's a few articles that come to mind on MP2Kmag that can help you get started --

Tracking P.F. Chang’s in the Midwest - MapPoint Articles - MP2K Magazine

Home Locator Sample Application - MapPoint Articles - MP2K Magazine

Using MapPoint from Word, Access and Excel - MapPoint Articles - MP2K Magazine

You could probably use any one of them to get started, but you will probably like the examples of all three.
