You will also have to setup your mapserver mapfile. Set the projection 
in the MAP section to be epsg:900913 and in your data LAYER set the 
projection to be that of your source data. Mapserver will reproject on 
the fly for you.

As far as accuracies, the data should overlay accurately, but I guess it 
all depends on what you expect to do with it. But you do not have 
another choice if you want to use Google maps as you base layer.

You will need to do some reading if you are not familiar with OpenLayers 
or Mapserver to work out the details, but I'm sure people on the list 
can help if you get stuck.
