Google Maps v3 multiple markers + geolocation

I'm making a web application for the university where I work. I need to plot multiple markers—for which I have lat/lon—and geolocate the user.

I've been able to do each of those tasks separately, just not on the same map.

Any help would be greatly appreciated.

Example of the locations: http://www.colum.edu/campusmap/

Put the locations into a KML file.

Note: Google Maps KML are lon, lat; not lat, lon
