Large Which parameter values should I use with QGIS Heatmap plugin?

I've read all the posts and docs about the heatmap plugin but can't seem to get it to work.

The map is the size of the United States and has a little over 2000 points. I've tried small radi (1 meter) and large radi (5 million meters), but still get a red hot map. 

I'm using QGIS 1.8 and WGS84. The data was initially in a spreadsheet, but I saved it as a .shp vector layer and deleted the old csv layer. 

The goal is to convert that to contour lines to map density of these points like in this Mapbox blog post. Suggestions?
