Hi Borys

Thanks a lot for the hint with google maps. It works like a charm!

There is no Google WMS, they are static tiles. The two plugins make two 
different workarounds to use them. OpenLayers Plugin is great for
display, 
however I expect big problems with proper printing, so wouldn't be 
optimistic...

I wonder if it's possible to use GoogleMaps in Qgis directly via GDAL
TMS 
driver. I'm able to open it, but can't cope with colors: Google serves
8bit 
pngs, while Qgis needs RGB. Maybe other gdal versions do it more
smoothly?

On the http://www.gdal.org/frmt_wms.html you have a link to the
OpenStreetMap 
TMS Service Example: 

http://www.gdal.org/frmt_wms_openstreetmap_tms.xml

Just download this file and open in Qgis as a raster. You shold see OSM
layer 
with proper or bad colors ;) In order to use googlemaps instead of OSM, 
replace the third line of the file with: 

<ServerUrl>http://mt0.googleapis.com/vt?lyrs=m@144&x=${x}&y=${y}
&z=${z}</ServerUrl>
