The first and very important thing that I had to do to get on the right track is to use the Blender default interaction preset instead of Maya.
By doing that I got the feeling what really Blender is instead of miss certain shortcuts used in Maya and got that feeling Maya works better for me. Of course using the Blender default interaction I have to learn tons of new things, but the more I learn about Blender the less I have the feeling that Maya is better. So it is a beginning of a long journey :)
Later I saw a Blender Conference presentation by Tangent Animation and Jeff Bell said exactly what I experienced about the Blender vs Maya interaction...so I know that I'm really on the right track.
