You could either correct them in AutoCAD, which is a better option, since their topology will be maintained, or you could import them into a geodatabase, and then use Spatial Adjustment ...

var polygon = new esri.geometry.Polygon(polygonJSON);
});

Basically you can do this by overlay vector(GPS data) on raster(world-map-image). If you want a map viewer to view both. you can use QGIS for desktop or if you want a web page, please consider OpenLayers/Leaflet.
Or you may be looking to create a png/jpeg image with both data on it. This case you can use qgis/grass/mapserver's shp2img. The easy way is ...

I can spot two things:
Change every instance of EPSG:900913 to EPSG:3857 -- EPSG:900913 (Or EPSG:GOOGLE if you squint hard enough) never existed in the EPSG database. It's a long story, but EPSG:3857 is the correct code.
It looks like you have one too many zeroes when you initialize your minLat and minLong variables. Compare it to your new ...
