I am trying to brainstorm the best way to track a users location.

I have accomplished this in another open source application but dotn know if its the same here.  I created an SQL Server express database that gets updated every few seconds from and Access Database that is reading the NMEA string from a GPS unit.  The application is using an OGR connection to read the SQL database table and create a graphic.

Wondering what my best approach would be in Silverlight app. 
Create an mxd that reads a SQL table and plots a point?
Can I read a SQL express database table and create a graphic with the specified coordinates? 

I then have to address the refreshing issue every few seconds.....

Anyone do this or have nay ideas?

There is no GPS tracking in Silverlight but you might be able to read GPS coordinates from JavaScript as they did in this sample: http://usamawahabkhan.blogspot.com/2010/03/silverlight-4-gps-navigation.html

I think you need to ask ArcGIS Server team on how you can define your data. You can also read up on the following help doc: http://help.arcgis.com/en/arcgisserver/10.0/help/arcgis_server_dotnet_help/index.html#//009300000021...
