Visualiser for spatial query results
I would use Excel 2013 - it has fairly easy Map integration which can take Lat+Lon, eg:

I would pull a SQL view through PowerPivot for easy derivation of .Lat and .Long, and for refreshing the data.

Alternatively SQL Server Reporting Services 2008 R2 or 2012 has similar Map integration, but the end user experience is static.
