For a recent project I was working on, I needed to overlay lines of latitude and longitude on the map. I had a hard time finding some so I created 10 degree and 30 degree grids. Below you can view each of them as a Collection which you can export to KML, GeoRSS or GPX and you can also grab the exported KML for each. I figured someone else must have use for this as well. If you grab the KML files you can easily edit the styles (1 for latitude, 1 for longitude) or make whatever tweaks you need.
10 Degree Lines: Collection or KML
30 Degree Lines: Collection or KML
