The "easiest" approach might be to use a mapping API, like the one from the G word, or MSN's version at:
In this way, you don't have to worry about map projection and coordinate translation... Just upload your collection of points (i.e., via the client-side API functions to add pincushions, etc), and let the API to the heavy lifting for you.

It really depends on your needs, I guess.
The simplest method (without using a free web-based mapping API) would be to get a flat graphic representing the map of your area, and then plot your points on the graphic (and connect each point with a line to the previous and next points). The challenge
with this is making sure that you know the projection that the map uses and the coordinates of the map boundaries so that you can accurately plot points inside of it (some complex trig math may be involved). This obviously won't be able to trace street vectors,
so if the street does not follow a straight line between two points, then your results will not be accurate.
As you move up into more advanced mapping needs, you'll probably want to use dedicated mapping software like MapPoint, ESRI, or MapInfo (and possibly Google Earth), just for the rich data and accuracy, if nothing else. These don't have to be used as packaged
software, btw. About 8 years ago, I saw MapInfo being used as part of a cargo delivery optimization software (you provide a daily manifest of deliveries for a city, and it could tell you how many trucks would be needed and what routes they would have to drive).
